Define a method named swapValues that takes an array of four integers as a parameter, swaps array elements at indices 0 and 1, a
Luba_88 [7]

The program is an illustration of arrays.

Arrays are used to hold multiple values.

The program in java, where comments are used to explain each line is as follows:

import java.util.*;

public class Main{

   //This defines the method

public static int[] swapValues(int[] arr) {

   //This swaps the first and second array elements

       int temp = arr[0];

       arr[0] = arr[1];   arr[1] = temp;

   //This swaps the third and fourth array elements

       temp = arr[2];

       arr[2] = arr[3];   arr[3] = temp;

   //This returns the swapped array to main

       return arr;

}

//The main method begins here

   public static void main(String[] args) {

       //This creates a Scanner object

       Scanner input = new Scanner(System.in);

 //This declares an array of 4 elements

 int[] intArray = new int[4];

 //This gets input for the array

 for(int i = 0; i<4;i++){

     intArray[i] = input.nextInt();

 }

 //This calls the swapValues method

 intArray=swapValues(intArray);

 //This prints the swapped array

 for (int i = 0; i < 4; i++){

 System.out.print( intArray[i]+ " ");     }

}  

}

At the end of the program, the elements are swapped and printed.

We have said that the average number of comparisons need to find a target value in an n-element list using sequential search is
bija089 [108]

Answer:

Part a: If the list contains n elements (where n is odd) the middle term is at index (n-1)/2 and the number of comparisons are (n+1)/2.

Part b: If the list contains n elements (where n is even) the middle terms are  at index (n-2)/2 & n/2 and the number of comparisons are (n+2)/2.

Part c: The average number of comparisons for a list bearing n elements is 2n+3/4 comparisons.

Explanation:

Suppose the list is such that the starting index is 0.

Part a

If list has 15 elements, the middle item would be given at 7th index i.e.

there are 7 indices(0,1,2,3,4,5,6) below it and 7 indices(8,9,10,11,12,13,14) above it. It will have to run 8 comparisons  to find the middle term.

If list has 17 elements, the middle item would be given at 8th index i.e.

there are 8 indices(0,1,2,3,4,5,6,7) below it and 8 indices(9,10,11,12,13,14,15,16) above it.It will have to run 9 comparisons  to find the middle term.

If list has 21 elements, the middle item would be given at 10th index i.e.

there are 10 indices (0,1,2,3,4,5,6,7,8,9) below it and 10 indices (11,12,13,14,15,16,17,18,19,20) above it.It will have to run 11 comparisons  to find the middle term.

Now this indicates that if the list contains n elements (where n is odd) the middle term is at index (n-1)/2 and the number of comparisons are (n+1)/2.

Part b

If list has 16 elements, there are two middle terms as  one at would be at 7th index and the one at 8th index .There are 7 indices(0,1,2,3,4,5,6) below it and 7 indices(9,10,11,12,13,14,15) above it. It will have to run 9 comparisons  to find the middle terms.

If list has 18 elements, there are two middle terms as  one at would be at 8th index and the one at 9th index .There are 8 indices(0,1,2,3,4,5,6,7) below it and 8 indices(10,11,12,13,14,15,16,17) above it. It will have to run 10 comparisons  to find the middle terms.

If list has 20 elements, there are two middle terms as  one at would be at 9th index and the one at 10th index .There are 9 indices(0,1,2,3,4,5,6,7,8) below it and 9 indices(11,12,13,14,15,16,17,18,19) above it. It will have to run 11 comparisons  to find the middle terms.

Now this indicates that if the list contains n elements (where n is even) the middle terms are  at index (n-2)/2 & n/2 and the number of comparisons are (n+2)/2.

Part c

So the average number of comparisons is given as

((n+1)/2+(n+2)/2)/2=(2n+3)/4

So the average number of comparisons for a list bearing n elements is 2n+3/4 comparisons.
