Solution: Partition Labels
Explore the two pointers technique to solve the partition labels problem, dividing strings into maximum contiguous parts so each character appears in only one part. Understand how to track the last occurrence of characters and dynamically adjust partitions to achieve optimal splits. Gain practical insights into efficient string partitioning useful for technical 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.
