“Sorting a list of numbers” Algo Example
Strategy statement
52
“Sorting a list of numbers” Algo Example
Strategy statement Use my “smallest number” algorithm to find the smallest number in the list. When found, swap it with the first item in the list and then consider the remaining list (from the 2nd item on) as the new list. Repeat this until only have one number left in the list.
53
“Sorting a list of numbers” Algo Example
Start with full list Remember where start of list is Do Run “smallest number” algorithm on list – get smallest number Swap smallest number with first number in list New list starts with 2nd item Until at last number Original list is now sorted
54
New list starts w/2nd item
Start w/full list Remember start of list Sorting Algorithm Flowchart Get smallest # Swap w/1st New list starts w/2nd item Last #? No Yes Orig list is sorted
55
// The list is in “myList” // Figure out where the last item in the list is. lastItem = myList.length - 1; // Point to the first item in the list. currItem = 0; do { // my algorithm returns the location of the smallest number locationOfSmallest = GetSmallestNumber( myList ); // Swap the smallest item with the first item temp = myList[currItem ]; myList[currItem ] = myList[ locationOfSmallest ]; myList[ locationOfSmallest ] = temp; // Point to the next item…”new” list is one smaller currItem += 1; } while ( currItem < lastItem );
