1405. Longest Happy String l Priority Queue l Greedy l String l LeetCode l Medium
In this video, we’ll tackle the popular LeetCode problem 1405. Longest Happy String. A “happy string” is a string made up of the characters ‘a’, ‘b’, and ‘c’ where no three consecutive characters are the same. The challenge is to construct the longest possible happy string given specific counts of each letter.
We’ll walk through the problem step by step, discuss an efficient approach, and then implement a solution in C++. By the end, you’ll understand how to maximize the length of the string while following the problem’s constraints!
