write c code

Suppose we number the bytes in a w-bit word from 0 (least significant) to w/8 -1 (most significant) Write code for the following C function, which returns an unsigned value in which byte i of argument x has been duplicated unsigned long long extend_byte (unsigned x, unsigned i); Here are some examples showing how the function should work: extend_byte (OxAB3F56, 0) > OxAB3F5656 extend_byte (OxAB3F56, 2) > OxABAB3F56
