Binary Search to Find Maximum k

  1. Initialize left to 0 and right to the length of the removable array.
  2. While left is less than or equal to right: a. Calculate mid as the average of left and right. b. Mark the characters at indices removable[0] to removable[mid - 1] in s as removed. c. Check if p is still a subsequence of the modified s. d. If p is a subsequence, set left to mid + 1 (try a higher k). e. If p is not a subsequence, set right to mid - 1 (try a lower k).
  3. Return right as the maximum k.
