Write a function called madLib that takes in a string and a dictionary.

The input dictionary will have keys that are integers and data values that are strings.

Your function should replace the word in the original string at each key value with the data for

that key value. Your function should return an updated string.

Ex: inputString = I like chocolate milk

InputDictionary = {0:we, 3:cookies}

Should return the string we like chocolate cookies

You may find the split() and str() functions for strings and lists to be useful.
