Longest Happy String With Greedy Approach

We can use a greedy algorithm to find the longest happy string by using a Priority Queue (Max Heap) and continuously extracting the character with the highest count while ensuring we don't exceed two consecutive occurrences of the same character.

1405. Longest Happy String
Difficulty: Medium
Topics: String, Greedy, Heap (Priority Queue)
A string s is called happy if it satisfies the following conditions:

s only contains the letters 'a', 'b', and 'c'.
s does not contain any of "aaa", "bbb", or "ccc" as a substring.
s contains at most a occurrences of the letter 'a'.
s contains at most b occurrences of the letter 'b'.
s contains at mostcoccurrences of the letter'c'`.

Given three integers a, b, and c, return the longest possible happy string. If there are multiple longest happy strings, return any of them. If there is no such string, re...
