I just read some code that applies a series of transformations to a 4 byte integer. I'm curious to know if the following function is invertible.

f(y) = y^(y>>11)

f(y) = y^(y>>11)

A general doubt I have, is the thought process involved when trying to find the inverse functions whenever a series of instructions are given. Do you have a methodology for approaching these kinds of problems?
