1. Dene a function chomp :: String -> String that selects a run of repeated characters from the start of a string with the run being as long as possible.

For example

chomp "aaaaaabbbbcccc" = "aaaaaa"
chomp "ddddddddddddd" = "ddddddddddddd"

2. Using chomp, dene a function
runs :: String -> [String ]
that splits a string into a list of runs of repeated characters, with each run comprising at most nine characters. For example:
runs "aaaaaabbbbcccc" = ["aaaaaa", "bbbb", "cccc"]
runs "ddddddddddddd" = ["ddddddddd", "dddd"]

3.Dene a function
flatten :: [(Char, Int)] -> String
that
attens a list of pairs of characters and digits to a string. For example:
flatten [(a, 5), (b, 4), (c, 2)] = "a5b4c2"
flatten [(d, 9), (d, 3)] = "d9d3"
