Assigning the number one to a random position of a 10x10 array

P: 1
I've created the array and I'm trying to work out how to assign the number one to a random position. The goal is to create a 'treasure hunt'.

Generate a random number between 0 and 9 for an index within an array (the X-position). Then generate another random between 0 and 9 for the index of the array to put the item in (the Y-position).

Once you have a random X and a random Y position, check to see if there is an item at that position. If there is, then generate new X and Y numbers until you find a position that is not taken.
