Write a function (such as placeAt) that takes an array of non-negative integers and an index that is a non-negative integer. It should place a 1 at the given index, possibly shifting other entries by one spot to vacate that spot, with 0's standing for empty spots.

Explanation:
Last year in math class, on homework we would occasionally get these extremely simple, although equally annoying questions called diamond puzzles.
