Remove All Adjacent Duplicates in String in C++

Open anushkadubey opened this issue 4 years ago • 1 comments

You are given a string s and an integer k, a k duplicate removal consists of choosing k adjacent and equal letters from s and removing them, causing the left and the right side of the deleted substring to concatenate together.

We repeatedly make k duplicate removals on s until we no longer can.

Return the final string after all such duplicate removals have been made. It is guaranteed that the answer is unique.

Example 1: Input: s = "abcd", k = 2 Output: "abcd" Explanation: There's nothing to delete.

Example 2: Input: s = "deeedbbcccbdaa", k = 3 Output: "aa" Explanation: First delete "eee" and "ccc", get "ddbbbdaa" Then delete "bbb", get "dddaa" Finally delete "ddd", get "aa"

Constraints: 1 <= s.length <= 105 2 <= k <= 104 s only contains lower case English letters.
