July 23, 2025 - Given a set of non-negative integers and a value sum, the task is to check if there is a subset of the given set whose sum is equal to the given sum. Below is the implementation of the Subset Sum Problem in javascript: ... // A Dynamic Programming solution for subset sum problem // Returns true if there is a subset of // set[] with sum equal to given sum function isSubsetSum(set, n, sum) { // The value of subset[i][j] will be // true if there is a subset of // set[0..j-1] with sum equal to i let subset = new Array(sum + 1); for(let i = 0; i < sum + 1; i++) { subset[i] = new Array(sum + 1); for

Use recursion to solve tricky problems and create algorithms that run exponentially faster than the alternatives. Dig into advanced data structures such as binary trees and graphs to help scale specialized applications such as social networks ...

January 25, 2024 - Naive search algorithm is used to find if a string contains a given substring. For example, check if "helloworld" contains the substring "owo". First loop on the main string ("helloworld"). Run a nested loop on the substring ("owo"). If character does not match then break inner loop else keep looping. If inner loop is completed and got a match, then return true else keep the outer loop going.

February 21, 2019 - Walk through solutions to common algorithms in JavaScript from the brute force method to the final, optimized solution. Tagged with javascript, algorithms.

July 19, 2021 - Having broken down this problem into smaller bits, we have a way to keep a copy of the original word given to us using the variable tool provided for us by JavaScript ... Since we cannot just reverse a string, we need to split the word and make it an array using the .split("") method

December 5, 2023 - Recursion is a method where the solution to a problem depends on solutions to smaller instances of the same problem. function factorial(x) { if (x === 0) return 1; return x * factorial(x - 1); } console.log(factorial(5)); // Outputs: 120 · That's a wrap on our intro to data structures and algorithms in JavaScript!

September 11, 2024 - A graphic representation of classic algorithm complexities · Note that the same notation is used when talking about both time and space complexity. Say for example we have a function that always creates an array with a single value no matter the input it receives, then the space complexity will be constant O(1), and so on with the other complexity types. To better understand all this, let's go back to our problem and analyze our solution examples.
