Shuffle

October 20, 2009

It is easy to shuffle an array by stepping through the array, swapping each element with a forward element (an element at an index greater than or equal to the current element) until the next-to-last element is reached. It is harder to shuffle a linked list, because lists don’t permit ready access to any element other than the first.

Your task is to write functions that shuffle an array and a linked list. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
