We are given an integer number let’s say, x and the task are to count the smaller numbers less than x whose XOR with x will result in a value greater than the XOR value.The truth table for XOR operation is given belowABA XOR B000101011110Input − int x = 11Output − Count of smaller values whose XOR with x is greater than x are − 4Explanation −We are given with the x as 11 which means we need to find XOR of x with the numbers less than x. So the numbers are 1 XOR 11 < 11(FALSE), 2 XOR ... Read More

We are given an integer number let’s say, num and the task is to count the smaller numbers less than num whose XOR with num will result in a value greater than the XOR value..The truth table for XOR operation is given belowABA XOR B000101011110Input − int num = 11Output − Count of smaller numbers whose XOR with n produces greater value are − 4Explanation −We are given with the num as 11 which means we need to find XOR of num with the numbers less than num. So the numbers are 1 XOR 11 < 11(FALSE), 2 XOR 11 ... Read More
