// MORE SUGGESTED HELPER FUNCTIONS FOR HW11
//
// In class, I said that ideally, a function should contain code at a given
// level of abstraction.  For example, a function that operates at the level
// of pixels should not contain any byte-level calculations.
//
// To the extent that you can follow this, it will make problems easier to think
// about because a given function will read at the same level of detail you
// would describe verbally.
//
// The helper functions below (just outlines, obviously) handle byte-level calculations
// so that code in your
