$2.$ We can use the REV instruction to perform conversion between $32-$bit little$-$endian and big$-$endian numbers. Write an assembly program that uses bitwise operators, such as $\backslash$&$,\backslash (1,\backslash$wedge$,\backslash$ll $\backslash ),$ and $\backslash (\backslash$gg $\backslash ),$ to implement the endian conversion. You cannot use REV in your program.
