In python

Design and implement encoder and decoder functions that perform run length compression of strings (https://en.wikipedia.org/wiki/Run-length encoding) a. Run length string encoder: The encoder function should take a string as a parameter, and return the encoded string, represented in a list. For example: Given the string: "aadccccaa" The encoded string will be: [['a', 2], ['d', 1], ['c', 4, ['a', 2] b. Run length sting dsoed take an encoded string (represente The decoder function should take an encoded string (represented in a list) as a parameter, and return the original string. For example: Given the encoded string: [['a', 2], ['d', 1], ['c', 4], ['a', 2]] The decoded string is: "aadccccaa" Note: Use the top down design approach to break the problem into smaller sub-problems that can be used to solve it
