Write RISC$-$V instructions to reverse the order of bytes in register s$2$ and save the results in s$4.$ For example, if s$2$ is $0$x$12345678,$ the four bytes in s$2$ are $0$x$12,0$x$34,0$x$56,$ and $0$x$78.$ Register s$4$ should be $0$x$78563412$ after the execution of the instruction sequence. Use temporary registers like t$0$ and t$1$ to save intermediate values.
