Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
what is an efficient sort algorithm?
A
an algorithm that accepts any data type
B
an algorithm that sorts a data set in a short time
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Quicksort. Quicksort is one of the most efficient sorting algorithms, and this makes of it one of the most used as well. The first thing to do is to select a pivot number, this number will separate the data, on its left are the numbers smaller than it and the greater numbers on the right.

Detailed explanation-2: -Q1. Which is the best sorting algorithm? If you’ve observed, the time complexity of Quicksort is O(n logn) in the best and average case scenarios and O(n^2) in the worst case. But since it has the upper hand in the average cases for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

Detailed explanation-3: -Quicksort is one of the most efficient sorting algorithms. It works by breaking an array (partition) into smaller ones and swapping (exchanging) the smaller ones, depending on a comparison with the ‘pivot’ element picked.

Detailed explanation-4: -Optimized Quicksort is clearly the best overall algorithm for all but lists of 10 records. Even for small arrays, optimized Quicksort performs well because it does one partition step before calling Insertion Sort.
