Hello @mohammadabdullahjawwad

You should NOT assign things to indices which do NOT exist. Like the length of the string “ans” is zero initially so you cannot use ans[1] = ‘A’ because index 1 does not exist.
What you can use is ans = ans + ‘A’ (This appends the character ‘A’ at the back of the string)

Try to print out the ans.length() at the end of your program, you will get 0 as the length.

Here is the modified code
