Solution: Split a String Into the Max Number of Unique Substrings

Explore how to solve the problem of splitting a string into the maximum number of unique substrings using backtracking. Understand the recursive process of testing all substring partitions, maintaining a set of seen substrings, and backtracking to find the optimal solution while ensuring uniqueness. This lesson helps you grasp combinatorial problem-solving techniques relevant to coding interviews.

Statement

Given a string, s, determine the maximum number of unique substringsA substring is defined as a continuous sequence of characters within a string. into which s can be split. You can divide s into any sequence of nonempty substrings, ensuring their concatenation reconstructs the original string. However, each substring in the split must be distinct.

Constraints:

  • 1 ...
