Suppose that a computer can run an algorithm on a problem of size 1,024 in time t. We do not know the complexity of the algorith
Setler79 [48]

Answer:

Time Complexity of Problem - O(n)

Explanation:

When n= 1024 time taken is t. on a particular computer.

When computer is 8 times faster in same time t , n can be equal to 8192. It means on increasing processing speed input grows linearly.

When computer is 8 times slow then with same time t , n will be 128 which is (1/8)th time 1024.

It means with increase in processing speed by x factor time taken will decrease by (1/x) factor. Or input size can be increased by x times. This signifies that time taken by program grows linearly with input size n. Therefore time complexity of problem will be O(n).

If we double the speed of original machine then we can solve problems of size 2n in time t.

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 String isbn;

 System.out.print("First 1:2 digits: ");

 isbn = input.nextLine();

 if(isbn.length()==12){

 int chksum = 0;

 for(int i = 0; i<12;i++){

     if((i+1)%2==0){      chksum+= 3 * Character.getNumericValue(isbn.charAt(i));          }

     else{          chksum+=Character.getNumericValue(isbn.charAt(i));          }  }

 chksum%=10;

 chksum=10-chksum;

 if(chksum==10){

 System.out.print("The ISBN-13 number is "+isbn+"0");}

 else{

 System.out.print("The ISBN-13 number is "+isbn+""+chksum);          }   }

 else{

     System.out.print("Invalid Input");

 }     }}
