Hey,

I’m not that familiar with java but i think you code will get NZEC error whenever string size is 1. string size is 1 and you are accessing value 1 which doesn’t exist.

from your code.

if(sb.charAt(0)==‘m’ && sb.charAt(1)==‘s’)

       sb.setCharAt(1,'k');

Hope this helps!

well,try the following test case:

2

s

m

you ought to check for corner case where |s| == 1.

further, in your first loop, you ought to change to condition from ( i< l ) to (i < l-1 ) to avoid StringIndexOutOfBoundsException.

No, you can’t see the test cases that are being used. You can see them on Codeforces and HackerRank(as far as I know), but not in codechef.
