What is the significance of the term 'divide and conquer' in merge sort?

The 'divide and conquer' strategy in merge sort involves breaking down the original unsorted list into smaller sublists, sorting those sublists, and then merging them back together in the correct order.

In merge sort, the 'divide and conquer' approach is about randomly shuffling elements

Merge sort does not involve dividing the list into sublists

The 'divide and conquer' strategy in merge sort means combining all elements at once

Describe the process of insertion sort algorithm.

The process of insertion sort involves selecting an element, comparing it with the elements before it, and inserting it into the correct position in the sorted part of the list.

Sorting elements in descending order

Selecting the largest element and placing it at the end

Inserting elements randomly without comparing

What is the role of a pivot element in quicksort algorithm?

The role of a pivot element in quicksort algorithm is to partition the array into two subarrays based on the pivot value.

The pivot element is used to sort the array in descending order

The pivot element is always the first element in the array

The pivot element is randomly selected from the array

Describe the process of bubble sort algorithm.

Bubble sort algorithm involves iterating over the list multiple times, comparing adjacent elements, and swapping them if they are in the wrong order. This process continues until the list is sorted.

Bubble sort algorithm selects the largest element in the list and moves it to the end in each iteration.

Bubble sort algorithm sorts the list by dividing it into subarrays and merging them together.

Bubble sort algorithm involves randomly shuffling the list elements until they are in order.

What is the key difference between linear search and binary search?

Linear search checks each element sequentially, while binary search divides the list in half.

Binary search is used for unsorted lists, while linear search is used for sorted lists.

Linear search is more efficient than binary search.

Linear search divides the list in half, while binary search checks each element sequentially.
