1. [25] Suppose we number the bytes in a 32 -bit word from 0 (least significant) to 3 (most significant). Write code for the following C function that will return an unsigned int consisting of byte 3 from x and bytes 2 through 0 from y : unsigned int combine (unsigned int x, unsigned int y ); Here are some test runs: combine (0x12345678, 0xABCDEF00): 0x12CDEF00 Use only bitwise operators; no if statements, loops, or arithmetic operators (+, - , ,/, \%). Also write an int main() function to test your function. Hint: use a bit mask to isolate byte 3 from x, and another bit mask to isolate bytes 2 through 0 from y, then combine the results. Comment your code, including every line that uses a bitwise operator. Name your source file 11.c
