1593. Split a String Into the Max Number of Unique Substrings

Leetcode Solutions

Backtracking with Set

  1. Define a helper function that takes the current index, the string, and a set of seen substrings.
  2. If the current index is at the end of the string, return 0, as there are no more substrings to process.
  3. Initialize a variable to keep track of the maximum number of unique substrings (max_count).
  4. Iterate over the string starting from the current index to the end of the string.
  5. At each iteration, create a new substring from the current index to the current iteration index.
  6. If the substring is not in the set, add it to the set and recursively call the helper function with the next index and the updated set.
  7. Update max_count with the maximum of its current value and 1 plus the result of the recursive call.
  8. Remove the substring from the set to backtrack.
  9. Return max_count.
