Rotate Right in a 32-bit Register

#include <stdio.h>

    // Ensure n is within the 0-31 range
    n = n % 32;

    if (n == 0) return reg;

    // Combine the right-shifted part and the wrapped-around left part
    return (reg >> n) | (reg << (32 - n));

        printf("%u\n", rotate_right(reg, n));
