Solution: Partition Labels
Explore how to solve the Partition Labels problem by using the two pointer technique combined with tracking the last occurrence of characters. Understand how to divide a string into maximum partitions where each letter appears only in one, enhancing your problem-solving skills for coding interviews.
We'll cover the following...
Statement
You are given a string s. Your task is to divide the string into as many parts as possible such that each letter appears in at most one part.
In other words, no character should occur in more than one partition. After concatenating all parts in order, the result should be the original string s.
For example, given s = "bcbcdd", a valid partition is ["bcbc", "dd"]. However, partitions like ["bcb", "cdd"] or ["bc", "bc", "dd"] are invalid because some letters appear in multiple parts.
Return a list of integers representing the sizes of these partitions.
Constraints:
s.length...
