Partition Labels

Explore how to solve the Partition Labels problem using the two pointers technique. Learn to divide a string into parts where each letter appears in only one partition, ensuring you can reconstruct the original string by concatenating the parts. This lesson helps you understand this common interview pattern and implement an efficient solution.

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 ...
