this is my code. Although I assigned the string as blank in the base case but it is still printing previous answer +new answer.
I feel like it does not create any difference to string upon assignment . Is that so?
Also how to correct the answer.
Printing wrong answers
@tanjuljain19
hello Tanjul,
In this line you will keep append new charater in the previous ans.
assigning null will not work becuase scope is local and for each function new copy of ans variable will be made.
to rectify it
