Well I was solving Buy1-Get1 from the practice problems(easy) and came across something strange
My code would get accepted if i took the string input as follows and then did the neccessary operations:
arr[(int)str[i]]++; // arr is just another array
But instead i was trying to take the input as follows and was doing the necessary operations:
----->NOTE:In the prob the user enters \n after giving number of testcases and i took the input as scanf("%d%*c",&t) so as to account for the ‘\n’ entered <-----
My code wouldn’t get accepted and gave WA for the below version.(the remaining code didn’t change for the two versions…)
Can someone please tell me whats wrong?
Thanks for the help!!!
