Insertion Sort: Introduction• Algorithm for sorting elements in array• Algorithm sorts the numbers in place• Do not have to allocate additional storage• Simply rearranges the numbers in the array
• “Left” side is always sorted• Will see in demonstration
• Java implementation will use ArrayLists and Generics • Anything that implements Java’s compareTo can be used
Insertion Sort: The Algorithm• Select the element to be compared• Start at the second element (index: 1) and continue to the last
element (index: array to be sorted length – 1)• Compare this element to elements preceding it • Exchange with preceding elements until the element to be
compared is greater than a preceding element or the start of the array is reached
• Repeat
