Problem
1. Using map, increase the value of a sound by applying a function to each sample of the sound.
2. Write a recursive function to jumble up all the characters in a string. The function will pick a random number representing the index of a character in the string (random.randint(1, len(word)) - 1); it will join together the two parts of the string on either side of the chosen character and call itself on that smaller string; and it will join the result to the chosen character. Like all recursive functions, it needs to know when to stop: if given a string of length 0 or 1, it will simply return that string.
3. Write a function that uses map to apply your jumbling function to a list of names and returns the result.
