Answer: "N" is considered as the size of the input that is being given in the algorithm.
Explanation: During a problem solving process , a algorithm is used to analyze the problem . Many function and steps are to be taken care of while analyzing algorithm. Among analyzing step, input is also given which is usually zero more than that . An input has a certain size which is given by the initial "N". The input size defines the length of the string for the input.
A computer system designed to run games is called a game console.
Answer:
// program in java.
// package
import java.util.*;
// class definition
class Main
{
// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// scanner object to read input
Scanner scr=new Scanner(System.in);
// string array
String name[] = new String[3];
// price array
double price[] = new double[3];
// variable
double sum = 0,avg;
boolean flag = false;
// read three name and their price
for(int i=0;i<3;i++)
{
System.out.print("Enter item "+(i+1)+" name:");
name[i]=scr.next();
System.out.print("Enter item "+(i+1)+" price:");
price[i]=scr.nextDouble();
sum=sum+price[i];
// if any name is "peas"
if(name[i].equalsIgnoreCase("peas"))
flag = true;
}
System.out.println("Name and their price:");
for(int i=0;i<3;i++)
{
System.out.println(name[i]+":"+price[i]);
}
// if flag is true
if(flag)
{
// calculate average
avg=sum/3;
// print average
System.out.println("Average price is:"+avg);
}
else
System.out.println("no average output");
}catch(Exception ex){
return;}
}
}
Explanation:
Read three name and their price from user.If any name is equal to "peas" without case sensitive then find the average of three price and print the average.If their is no name equal to "peas" then print "no average output".
Output:
Enter item 1 name:apple
Enter item 1 price:20
Enter item 2 name:kiwi
Enter item 2 price:15
Enter item 3 name:banana
Enter item 3 price:20
Name and their price:
apple:20
kiwi:15
banana:20
no average output
