Explanation: The input binary string 11111111111111111111111111111101 represents the unsigned integer 4294967293, so return 3221225471 which its binary representation is 10111111111111111111111111111111. Note: Note that in some languages such as Java, there is no unsigned integer type. In this case, both inpu...
