3. Selection Sort
• The idea in a selection sort is that you locate the largest item out of a set of
unsorted items, and move it into position at the end of the unsorted items. A
sorted region grows one item at a time, while an unsorted region shrinks.
• As done in Part 1, fill an array with random numbers.
• Write a function that locates the largest element in the portion of the array
beginning at the start of the array, up to a given index, and swaps the largest
item with the item at the given index.
• E.g. If searching a[0] to a[7] locates the largest item at a[4], a[4] and a[7] would be
swapped.
• Write a second function that calls the first function repeatedly, until the entire
array is sorted. (Each time the first function is called, it will search one fewer
element)
