Web2 hours ago · Given an integer A. Two numbers, X and Y, are defined as follows: X is the greatest number smaller than A such that the XOR sum of X and A is the same as the sum of X and A. Y is the smallest number greater than A, such that the XOR sum of Y and A is the same as the sum of Y and A. Find and return the XOR of X and Y. WebTo check a bit, shift the number n to the right, then bitwise AND it: bit = (number >> n) & 1U; That will put the value of the nth bit of number into the variable bit. Changing the nth bit to x. Setting the nth bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); university of miami health log in
