Could not understand my mistake, failing testcase 2 and 7

#1

please help me in finding the error in my code
link to the code https://ide.codingblocks.com/s/298060

In line number 16 you are jsut checking:
if(strmp[s[i]]<=mp[s[i]]){
cnt++;
}

Here if mp mp itself is 0. Then it will not be a valid move. So put a condition that when mp[s[i]]!=0 then you have to increase the count.
