Question
Which of the following algorithm pays the least attention to the ordering of the elements in the input list?Insertion sort Selection sort Quick sort None
Solution
The algorithm that pays the least attention to the ordering of the elements in the input list is the Selection Sort.
Here's why:
-
Insertion Sort: This algorithm sorts the list by shifting elements one by one. It heavily depends on the order of the input. If the input is already sorted, it performs at its best. However, if the input is in reverse order, it performs at its worst.
-
Selection Sort: This algorithm sorts an array by repeatedly finding the minimum element from the unsorted part and putting it at the beginning. The order of the input doesn't affect its performance, making it indifferent to the input order.
-
Quick Sort: This algorithm is a divide and conquer algorithm. It picks an element as a pivot and partitions the given array around the picked pivot. The performance of Quick Sort heavily depends on the choice of the pivot. If the pivot is chosen such that it's always one of the ends of the array, the worst case occurs for already sorted or reverse sorted arrays.
So, among the three, Selection Sort pays the least attention to the ordering of the elements in the input list.
