Write an expression that reverses the bytes of an integer x. That is the least significant byte should be swapped with the most significant byte, but the bits within each byte should remain in their original order. Simple code, no while/for loops.

For example, 0xABCD1234 should be turned into 0x3412CDAB

public static int Q7(int x) { return 0; }

public static void main(String[] args) {

assert Q7(x: 0xAABCD1234) == 0x3412CDAB
