@premang you are missing the case when the last character is unique and not printing that.
For example let’s say the test case is
abcde
your code gives output as a1b1c1d1
but the output should have had been a1b1c1d1e1.
So add this ‘else if’ statement after the condition where you are checking if(i==len-1 && str[i]==str[i-1])

		else if(i==len-1)
			cout<<str[i]<<"1";

Your code works after this.
