Solution: Partition Labels
Explore the solution to the Partition Labels problem by understanding how to use the two pointers technique combined with a last occurrence map. This lesson helps you learn to divide a string into the maximum number of partitions where each letter appears in only one part, improving your approach to string partitioning problems.
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.
