Quicksort algorithm implementation in java
As the name, quicksort is the quickest algorithm to sort some numbers. There are some other sorting algorithms like bucket sort, insertion sort, bubble sort, radix sort, etc. Among them, quicksort is very efficient. The efficacy of quicksort in the worst cause is
Here is the step diagram of quicksort:

Let's look at the Quick sort algorithm implementation in java code:
Happy Coding...

Here is the animated simulation of a quick sort algorithm.
If we look closely, the quick sort algorithm selects the last position of the array and assumes it as a pivot. It took two variables and assign the most left and the most right value of the array. Then it compares them with the pivot and swap if the left number is smaller than then the right number.
The algorithm steps will explain the quick sort easily:
The algorithm steps will explain the quick sort easily:
Step 1 − First, Choose the highest index value of array has pivot Step 2 − Take two variables and assign the most left and the most right value of the array excluding pivot Step 3 − left variable points to the low index of the array Step 4 − right variable points to the high index of the array Step 5 − if value at left variable is less than pivot, move right Step 6 − if value at right variable is greater than pivot move left Step 7 − if both step 5 and step 6 does not match swap left and right Step 8 − if left ≥ right, the point where they met is new pivot.
Happy Coding...
