Hello @ayush15goel,

You have to apply a logic before performing the swapping logic in the loop to check if you should perform swapping or not:

  1. if a[j] has already occurred between index i to j-1, then you should not swap as this will cause duplicate copy.

  2. Even if you will successfully implement this logic, your code would not work for all test cases as it would not print strings in sorted order
    Example: ABCC

Try hard to remove all the logical errors.
Hope, this would help.
If you still face problem, feel free to ask.
Give a like, if you are satisfied.
