Splitting Strings Into Max Unique Substrings
Split string into max unique substrings using backtracking & set for uniqueness. Recursive function explores all possible substrings, backtracks if repetition occurs.

Split a String Into the Max Number of Unique Substrings Difficulty: Medium Topics: Hash Table, String, Backtracking Given a string s, return the maximum number of unique substrings that the given string can be split into. You can split string s into any list of non-empty substrings, where the concatenation of the substrings forms the original string. However, you must split the substrings such that all of them are unique. A substring is a contiguous sequence of characters within a string. Example 1: Input: s = "ababccc" Output: 5 Explanation: One way to split maximally is ['a', 'b', 'ab...
