Algorithm we use:

  1. first find the subarray which contains all elements in the string2.
  2. Now we try to minimise this subarray from the start. How ?
    we keep removing the element we dont need from the start.
  3. When youu are done with the 2nd step, update your answer.
  4. Now repeat the first step by moving forward in the string1.

Now try to implement your code :slight_smile:
