All test case are not pass in char change problem

#1

My all test case are not passing, where am i going wrong?

#2

Please note that not only ‘a’ but the substring can also be only made up of ‘b’, you need to consider both cases.

#3

in the last nested loop, i have also considered case of b also. Please check it

#4

Yes, I see (my bad :frowning: ).

Please note that you are using the same variable ‘i’ for both the loops (main loop and the nested one) also you probably want to run the second loop from i and not always from 0.

ya, all test case passed. Thank you
