C++ Recursive *Quick Sort* 1. Please modify the PARTITION function below so that the array gets sorted from least to greatest. 2. pass the quickSort function an array with the following values: 5, 2, 6, 1, 3, 4 ... run the program and show a screenshot showing that it works.

double arr[] = {5, 2, 6, 1, 3, 4};

quickSort(arr, 0, 6);

for (int i = 0; i

Thank YOU!!!

PS: do not change the pivot. Our pivot must be the first element of the array. (what I mean by this is, that there different ways to choose a pivot. You can select a random pivot, make the middle number your pivot, or the last number of the array your pivot... etc... for this assigment, we are required to choose the first number in the array as our pivot)
