Problem: Partition Labels

Medium

30 min

Understand how to divide strings into partitions where each letter occurs in at most one part using two pointers. This lesson guides you through efficiently solving the problem and returning partition sizes, helping you master a common coding interview pattern.

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:

$1\leq$ s.length $\leq500$
s consists of lowercase English letters.
