What Is Dynamic Programming?

Before we get into all the details of how to solve dynamic programming problems, it’s key that we answer the most fundamental question:

How many times is the number 3 repeated in a tree?

Notice how we see repeated values in the tree. The number 3 is repeated twice, 2 is repeated three times, and 1 is repeated five times. Each of those repeats is an overlapping subproblem. There is no need for us to compute those subproblems multiple times because the value won’t change.

How to use brute force?

There are a couple of restrictions on how this brute force solution should look: 1 Each recursive call must be self-contained. If you are storing your result by updating some global variable, then it will be impossible for us to use any sort of caching effectively. We want to have a result that is completely dependent on the inputs of the function and not affected by any outside factors. 2 Remove unnecessary variables. The fewer variables you pass into your recursive function, the better. We will be saving our cached values based on the inputs to the function, so it will be a pain if we have extraneous variables.

What does overlapping subproblems mean?

Overlapping subproblems is the second key property that our problem must have to allow us to optimize using dynamic programming. Simply put, having overlapping subproblems means we are computing the same problem more than once.

What is the first problem we’re going to look at?

The first problem we’re going to look at is the Fibonacci problem. In this problem, we want to simply identify the n-th Fibonacci number. Recursively we can do that as follows:

What happens if you don’t have overlapping subproblems?

This is exactly what happens here. If we don’t have overlapping subproblems, there is nothing to stop us from caching values. It just won’t actually improve our runtime at all. All it will do is create more work for us.

What is optimal substructure?

Optimal substructure is a core property not just of dynamic programming problems but also of recursion in general. If a problem can be solved recursively, chances are it has an optimal substructure.

What is dynamic programming?

Dynamic programming is an algorithmic process that computer engineers and programmers use to solve optimization problems. When integrating dynamic programming into a software development project, for instance, the algorithm that DP uses breaks down complex coding problems into subproblems. Programmers can then apply the optimized solution to the entire problem, depending on the type of solution they derive from each subproblem in the code.

What is bottom up tabulation?

In the bottom-up method (or tabulation method), instead of applying recursion, you solve all the related sub-problems first. As bottom-up tabulation requires multiple solvencies, dynamic programming uses a dimensional table, or an n-dimensional table, where n represents a value of zero or greater. As you solve each subproblem within the table, you can then use the results to compute the original problem.

What is optimal substructure property?

This means that when solving each subproblem, the solution you calculate from each overlap must apply to the overall problem in order to function and optimize recursion in your programming. In the example of the Fibonacci sequence, each subproblem contains a solution that you can apply to each successive subproblem to find the next number in the series, making the entire problem display optimal substructure property.

What are subproblems in programming?

Subproblems are simply smaller variations of an original, larger problem. For example, in the Fibonacci sequence, each number in the series is the sum of its two preceding numbers (0, 1, 1, 2, 3, 5, 8 and so on). If you want to calculate the nth Fibonacci value in the sequence, you can break down the entire problem into smaller subproblems. These subproblems then overlap with one another, as you find solutions by solving the same subproblem repeatedly. The overlap in subproblems occurs with any problem, which allows you to apply dynamic programming to break down complex programming tasks into smaller parts.

How does top down work in dynamic programming?

In the top-down method of dynamic programming, you solve the overall problem before you break it down into subproblems. This process is memoization and works to solve larger problems by finding the solution to subproblems recursively, caching each result. This process of memoization helps to avoid solving the problem repeatedly in the event you need to call it more than once. With the top-down method, you can simply return the result you save as you solve the overall problem, thus storing results of problems you’ve already solved.

What are the characteristics of dynamic programming?

Characteristics of dynamic programming. Dynamic programming takes on two important characteristics, which make it a viable and effective tool for reducing programming time and boosting program functionality and efficiency:

What Is Dynamic Programming?

Dynamic programming is an algorithmic paradigm that divides broader problems into smaller subproblems and stores the result for later use, eliminating the need for any re-computation. This problem-solving approach is quite similar to the divide and conquer approach.

A classic example of a one-changing-parameter problem is “determine an n-th Fibonacci number”. Such an example for a two-changing-parameters problem is “Compute edit distance between strings”. If you’re not familiar with these problems, don’t worry about it.

What is DP in math?

First, let’s make it clear that DP is essentially just an optimization technique. DP is a method for solving problems by breaking them down into a collection of simpler subproblems, solving each of those subproblems just once, and storing their solutions. The next time the same subproblem occurs, instead of recomputing its solution, you simply look up the previously computed solution. This saves computation time at the expense of a (hopefully) modest expenditure in storage space.

How to determine the number of changing parameters?

A way to determine the number of changing parameters is to list examples of several subproblems and compare the parameters. Counting the number of changing parameters is valuable to determine the number of subproblems we have to solve. It’s also important in its own right in helping us strengthen the understanding of the recurrence relation from step 1.

Why can’t a problem be simplified further?

The reason a problem cannot be simplified further is that one of the parameters would become a value that is not possible given the constraints of the problem.

Do tech companies ask DP questions?

Many tech companies like to ask DP questions in their interviews. While we can debate whether they’re effective in evaluating someone’s ability to perform in an engineering role, DP continues to be an area that trips engineers up on their way to finding a job that they love.

Can a problem be solved using DP?

Recognizing that a problem can be solved using DP is the first and often the most difficult step in solving it. What you want to ask yourself is whether your problem solution can be expressed as a function of solutions to similar smaller problems.

How to avoid complexity in programming?

What are optimal substructure and overlapping subproblems?

Optimal substructure and overlapping subproblems are the two attributes a problem must have to be solved used dynamic programming. You will need to verify this when your intuition tells you dynamic programming might be a viable solution.

What is optimal substructure?

A problem has optimal substructure if the optimal solution to a problem of size n can be derived from the optimal solution of the same instance of that problem of size smaller than n.

How many variables are needed to compute Fibonacci?

This approach could be further optimized in memory, not time (there are faster techniques to compute Fibonacci numbers, but that is a topic for another article), by using just 3 variables instead of an array since we only need to keep track of 2 values, f (n-1) and f (n-2), to produce the output we want, f (n).

What is a subsequence in a string?

A subsequence of a string is a new string generated from the original string with some characters (can be none) deleted without changing the relative order of the remaining characters. (eg, “ace” is a subsequence of “abcde” while “aec” is not). A common subsequence of two strings is a subsequence that is common to both strings.

What is parsing in a lexer?

The parser analyzes the tokens and lexemes produced by the lexer program and creates an abstract syntax tree (AST). The parser utilizes a context-free grammar, the specification of the syntax. In a grammar, symbols called nonterminals are defined by productions, sequences of tokens and nonterminals. Algorithms such as LALR or Earley may be used, and the parser may be table-driven or handwritten.

What is a lexer in JavaScript?

The lexer accepts the program as an input and tokenizes it, or splits it into substrings with semantic meanings. The tokens may be defined by regular expressions. The lexer’s output has two parts: the lexemes, which are the different substrings of the program, and the tokens, which are lexemes’ classifications. For example, the JavaScript code var x = 0; could be separated into the following tokens:

What is an interpreter in Python?

Hint: An interpreter is a program that reads and executes the code directly without using the compilation process. Because of these factors, Python is often considered one of the best options for beginners, although it may not be as powerful when it comes to some more high-performance tasks.

1 Introduction

In this tutorial, we will build our own programming language and compiler using Java (you can use any other language, preferably object-oriented). The purpose of the article is to help people who are looking for a way to create their own programming language and compiler.

2 Lexical analysis

First of all, we will start with the lexical analysis. Let’s imagine you got a message from a friend with the following content:

3 Syntax analysis

Within our compiler model, the syntax analyzer will receive a list of tokens from the lexical analyzer and check whether this sequence can be generated by the language grammar. In the end this syntax analyzer should return an abstract syntax tree.

4 ToyLanguage

We finished with the lexical and syntax analyzer. Now we can gather both implementations into the ToyLanguage class and finally run our language:

5 Wrapping Up

In this tutorial, we built our own language with lexical and syntax analysis. I hope this article will be useful to someone. I highly recommend you to try writing your own language, despite the fact that you have to understand a lot of implementation details. This is a learning, self-improving, and interesting experiment!

Introduction

I’ll spare you a boring lecture on how computers understand only ones and zeroes, and they have to somehow translate your high-level instructions into something they can digest. Let’s just say that source code we humans perceive as a structure:

Splitting up the input

So the first order of business is to split up the input into words, numbers and so on. Here I’ll use a very simple rule: just split at whitespace. If this seems like a cheap cop-out, look at your own source code: most likely, you have whitespace everywhere, anyway.

Interpreting stuff

We have some input, now to make sense of it. Most programming languages have baroque rules for chaining keywords and punctuation into ellaborate constructs. (Just for kicks, check out the Wikipedia article on Recursive descent parsers .) But since we started simple, let’s keep it simple:

Basic words

What’s the most basic thing you can do with things on the stack? Why, print them, of course!

Fiddling with the stack

This is all fine and dandy, but what if you need more complex manipulations? Here are some stack operations that might prove useful.

In this tutorial, we will build our own programming language and compiler using Java (you can use any other language, preferably object-oriented). The purpose of the article is to help people who are looking for a way to create their own programming language and compiler.

2 Lexical analysis

First of all, we will start with the lexical analysis. Let’s imagine you got a message from a friend with the following content:

3 Syntax analysis

Within our compiler model, the syntax analyzer will receive a list of tokens from the lexical analyzer and check whether this sequence can be generated by the language grammar. In the end this syntax analyzer should return an abstract syntax tree.

4 ToyLanguage

We finished with the lexical and syntax analyzer. Now we can gather both implementations into the ToyLanguage class and finally run our language:

5 Wrapping Up

In this tutorial, we built our own language with lexical and syntax analysis. I hope this article will be useful to someone. I highly recommend you to try writing your own language, despite the fact that you have to understand a lot of implementation details. This is a learning, self-improving, and interesting experiment!

What is a parser in a program?

We build a parser: the parser is the part of our compiler that takes the text of our programs and understand which commands they express. It recognizes the expressions, the statements, the classes and it creates internal data structures to represent them. The rest of the parser will work with those data structures, not with the original text

Why is it important to build a compiler?

Building a compiler is the most exciting step in creating a programming language. Once we have a compiler we can actually bring our language to life.

What is a compiler?

A compiler figures out everything a program will do, turns it into “machine code” (a format the computer can run really fast), then saves that to be executed later.

What are the two types of languages?

There are two major types of languages: compiled and interpreted: 1 A compiler figures out everything a program will do, turns it into “machine code” (a format the computer can run really fast), then saves that to be executed later. 2 An interpreter steps through the source code line by line, figuring out what it’s doing as it goes.

Why do you write in compiled language?

If you are writing an interpreted language, it makes a lot of sense to write it in a compiled one (like C, C++ or Swift) because the performance lost in the language of your interpreter and the interpreter that is interpreting your interpreter will compound.

Why do I choose C++?

I chose C++ because of its performance and large feature set. Also, I actually do enjoy working in C++.
