// introduce partially fille arrays
// a partially filled array has 2 sizes associated with it:
// 1. capacity (how much space it has for elements) equals .length
// 2. actual number of elements
// when processing a partially filled array, loop
// for the number of elements, NOT:
// (a) until numbers.length
// (b) enhanced for loop
