Explanation / Answer

Solution1:

Use the following information for question 20-22.

20. What is the contents of the array after first iteration of selection sorting?

Exaplanation:

arr[] = {60,50,20,30,40};

In Selection Sorting

Iteration 1

arr[] = {20,50,60,30,40}

Hence, The correct answer is C. {20,50,60,30,40}

21. What is the contents of the array after first iteration of Insertion sorting?

Exaplanation:

arr[] = {60,50,20,30,40};

In Insertion Sorting

We are comapare first two element in array and exachange the place

after First iteration array will become

arr[] = {20,50,60,30,40};

Hence, The correct answer is C.

21. What is the contents of the array after first iteration of bubble sorting?

Exaplanation:

arr[] = {60,50,20,30,40};

In Bubble Sorting

first Iteration is below:

{60,50,20,30,40};

{50,60,20,30,40};

{50,20,60,30,40};

{50,20,30,60,40};

{50,20,30,40,60};

First Iteration is completed

arr[] = {50,20,30,40,60};

Hence, The correct answer is A.

60 50 20 30 40
