Submit a C file with the following two functions defined. unsigned char permutation (unsigned char x) unsigned char inverse(unsigned char y) The first C function should implement any non-trivial permutation function (ie, a one-to-one and onto function from byte to byte) of your choosing using at least three C operations. For the function to be invertible, each individual operation you choose has to be invertible too, so think about what combination of C operations are invertible and string three or more of them together. The second C function should be the inverse of the first C function. If you're successful, x == inverse (permutation(x)) should be true for every x. The file you submit should be named exactly hw1_permutation.c
