Hi @shantanu.kaushik21,see you in the function you can have a variable cc=str.charAt(0) now if cc==‘x’ then call the function again using str.substring(1) and store that ans in String ans and then do ans=ans+‘x’ else you call the function with str.substring(1) and store that ans in String ans and later do ans=cc+ans.
