Solution: Partition Labels
Explore how to solve the Partition Labels problem using a two pointers technique and a character last-occurrence map. This lesson helps you understand how to efficiently segment a string so that each letter appears in at most one part, optimizing for maximum partitions. You will learn how to implement this solution in Go with linear time and constant space complexity, improving your grasp of two pointer pattern and string manipulation.
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.
