Looks like you mostly figured it out. You need to be careful, however, about what it means to delete a number in your array. In your implementation, you are changing that number to a zero.

Many people would expect that number to go away completely, and the array to become one shorter in length, meaning that any array entries greater than the one deleted will change positions by one.
