Partition Labels
Detailed guide and Python implementation for the 'Partition Labels' problem.
Problem Statement
You are given a string s. We want to partition the string into as many parts as possible so that each letter appears in at most one part. Return a list of integers representing the size of these parts.
Write a function partitionLabels(s: str) -> List[int].
- •1 <= len(s) <= 500
- •s consists of lowercase English letters
Examples
s = "ababcbacadefegdehijhklij"
[9,7,8]
The partition is "ababcbaca", "defegde", "hijhklij".
s = "eccbbbbdec"
[10]
All characters in 'eccbbbbdec' can only be in one group.
