When given two strings, the goal is simple: determine whether they are anagrams of each other. An anagram is defined as a string that, when its letters are rearranged, forms another string. Both strings must have the same characters in the same frequency, regardless of the order. Let’s walk through a clean, structured approach to…
In this post, we’re going to tackle the Two Integer Sum problem. Given an array of integers and a target sum, the task is to return the indices of two numbers whose sum equals the target. The solution needs to return the indices in increasing order. This is a common algorithm problem that can be…
Alright, let’s talk about duplicates. You’ve got an array of numbers, and your job is to figure out if any of those numbers make more than one appearance. Seems simple, right? Well, as straightforward as it may sound, this is one of those classic coding problems that gets right to the heart of efficient problem-solving….
