/* Return a version of the given array where all the 10's have been removed. 
 * The remaining elements should shift left towards the start of the array as 
 * needed, and the empty spaces a the end of the array should be 0. So 
 * {1, 10, 10, 2} yields {1, 2, 0, 0}. You may modify and return the given 
 * array or make a new array.
