Write a function rle() that takes a list as input and returns another list with it’s run length encoding. as always, the input list should not be modified in any way.

problem 6b – rle. py: run length decompression [10 points] write a function unrle() that takes the run length encoding as input and returns the original list. this is the inverse of the previous function (i. e., for anylistl, it’salwaystruethatunrle(rle(l)) == l).onceagain, way.

note: you can assume that all values in the encoding are immutable (i. e., you do not need to worry about making copies of the value component of each run).
