![]() ![]() Line 21 (Fig 3) :- Here we are performing the swapping but for greater value in comparison to pivot. Now we are comparing our first element with pivot and make them swap (for putting smaller values in left). User defined functions are the ones which are written by the programmer based on the requirement. The two sub-arrays are divided in a way that one of them holds smaller values than the pivot value, and the other holds greater values than the pivot. The sorting algorithm first divides the array into two sub-arrays by comparing all elements with a specified value, called the Pivot value. ![]() Learn more about bidirectional Unicode characters. Quick sort is an ideal solution for a large set of data. To review, open the file in an editor that reveals hidden Unicode characters. so starting our loop from starting index which is 0 in this case and make it till last index. Quick Sort in C++ Raw QuickSort.cpp This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. Line 10 (Fig 3) :- Now we are iterating a for loop for putting the smaller values the pivot in left and greater values in right. Now in line 7 we are taking last element of array as pivot and in next line we are considering an integer as carrying the value of first index, we will use iIndex in further program. Line 5 (Fig 3) :- Here we are applying the partition by taking parameter as array, starting index and last index. Let’s understand the purpose of partition first, as this algorithm says to choose a pivot and then put all lesser value then pivot in left and greater values in right, means the smaller value in comparison to pivot will be in left and the greater value in comparison to pivot will be in right to the pivot in array. ![]()
