The Is Subsequence problem from LeetCode 75 is a popular interview question that checks your understanding of character matching, greedy algorithms, and two-pointer traversal. The task is simple: determine if one string is a subsequence of another. But to do it efficiently, especially when dealing with long strings, is where the value lies. In this … Read more
Move Zeroes is a classic array manipulation problem from the LeetCode 75 challenge list. It evaluates your grasp of in-place updates, the two-pointer approach, and efficient iteration techniques. While the objective—moving all zeroes to the end of the list—might appear straightforward, performing the operation in-place, without disrupting the order of non-zero elements, adds a layer … Read more
String Compression is a classic array manipulation problem from LeetCode75 that tests your understanding of two-pointer traversal, in-place operations, and character grouping logic. While the task might sound simple compressing repeated characters doing it efficiently and in-place without using extra memory adds an interesting twist. In this blog post, we’ll take you through the String … Read more

Introduction The Reverse Words in a String problem is a classic string manipulation challenge that appears frequently in coding interviews and is part of the LeetCode 75 study plan. Given a string s, reverse the order of the words in the string. Example 1: Example 2: Constraints: Python Solution for Reverse Words in a String … Read more
Introduction The Reverse Vowels of a String problem is a popular string manipulation challenge that tests your ability to selectively modify characters within a string. Given a string s, the task is to reverse only the vowels—both lowercase (a, e, i, o, u) and uppercase (A, E, I, O, U)—while keeping all non-vowel characters in … Read more
Introduction The Can Place Flowers problem is a classic greedy algorithm challenge frequently featured in coding interviews and study plans like LeetCode 75. In this problem, you’re given a binary list called flowerbed where 0 represents an empty plot and 1 represents a plot with a flower already planted. Along with this, you’re given an … Read more
Introduction You are given an integer array candies where each element represents the number of candies a particular child has. You are also given an integer extraCandies which represents the number of extra candies you can give to any one child. Your task is to determine for each child if they can have the greatest … Read more
