Chapter 9, Problem 1MC

Program Description Answer

The sorting is a type of algorithm which arranges the value in particular order.

Hence, the correct answer is option “B”.

Explanation of Solution

Sorting:

When contents of the array being arranged in the particular order is called as sorting. The order of arranging the contents can be ascending or descending order.

Types of sorting:

• Bubble sort
• Selection sort
• Insertion sort
• Merge sort
• Quick sort
• Shell sort
• Heap sort

These sort have the possibility of sorting the array in both ascending and descending order.

Ascending order:

When the elements present in the array are sorted from the lowest to highest is called as ascending order.

Example:

Consider the elements of array that are present in the ascending order below:

2, 4, 6, 8, 10… 20

Descending order:

When the elements present in the array are sorted from the highest to lowest is called as descending order.

Example:

Consider the elements of array that are present in the descending order below:

55, 45, 40, 35, 30 … 10

Explanation for incorrect options:

Search Algorithm:

The “searching” algorithm the process of searching for a particular element that is present in the array.

Hence, the option “A” is wrong.

Ordering Algorithm:

The term “ordering algorithm” is not an valid algorithm.

Hence, the option “C” is wrong.

Selection Algorithm:

The term “selection algorithm” finds the k^th smallest number in a list or array.

Hence, the option “D” is wrong.
