Today, I’m working on learning about how to solve Leetcode 69: Sqrt(x) The Problem: Given a non-negative integer x, compute and return the square root of x. Since the return type is an integer, the decimal digits are truncated, and only the integer part of the result is returned. Note…

In an effort to expand and keep growing my knowledge, I’ve taken up learning Node.js to further build my backend skills. If you’ve dipped your toes into the backend, I’m sure you’ve come across references to MongoDB. What is MongoDB? MongoDB is a NoSQL database — meaning that it uses collections and documents…

Today, we’re going to be solving Leetcode’s Problem #26, Remove Duplicates from Sorted Array. The Problem Statement:

What is GitHub? GitHub is an open-source site that provides users with tools to manage their projects and documentation. Developers can store and show off their code — and allow other users, from all over the world, to view and even improve on it. Through it, you can share your code and collaborate…

I’m working on another easy one today, “Contains Duplicate”. I’m proud of myself for how far I had gotten on my own with this one. (I’m getting better~ 😊) The Problem: Given an integer array nums, return true if any value appears at least twice in the array, and return…

The Problem:

The Problem: Given a string s containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid. An input string is valid if: Open brackets must be closed by the same type of brackets. Open brackets must be closed in the correct order. …

Solution: //change the number to a string and reverse //to string will have to be split and joined back together // then, we have to compare it to the original string var isPalindrome = function(x){ return x.toString().split("").reverse().join("") === x.toString() }; ✨✨✨And that’s it! Tish⚡️🎧🌙

Example 1: Input: nums = [2,7,11,15], target = 9 Output: [0,1] Explanation: Because nums[0] + nums[1] == 9, we return [0, 1]. Understanding the problem: Per the example above, if we start with 2, and we want to reach 9 — we need to add 7 from the array. …
