Show the complete implementation of quick sorting algorithm
on the next arrays examples
Step 1
Determine pivot
Step 2
Start pointers at left and right
Since 4> 3, stop
Step 3
Since 53, shift right pointer
Since 3 = 3, stop
Step 4
Swap values at pointers
Step 5
Move pointers one more step
Step 6
Since 2<3, shift left pointer
Since 4> 3, stop
Since left pointer is past right
pointer, stop
Example. Sort {1, 12, 5, 26, 7, 14, 3, 7, 2}
using quicksort.
