Partition Labels

Understand how to use the two-pointer technique to partition a string into parts where each letter appears at most once. This lesson helps you identify and implement an efficient solution to the partition labels problem, preparing you to tackle similar coding interview challenges with strings.

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 ...
