Task $1.$ MTUHash Implementation $(70$ ponts$)$

The MTUHash takes a message $($to be hashed$)$ as input and outputs a fixed $32-$bit value. Note that

the output with $32-$bit length is not very secure in practice. Here is a simplification of the problem.

We assume that the input message has a fixed length of $32$ bits. It is a simplification of the problem.
