Question

Given the following program: 

int x, y, z;

for (x = 1; x <= N; x++)

{

    for (y = 1; y <= N; y++)

{

System.out.println(x); 

System.out.println(y);

System.out.println(x+y);

System.out.println(x*y);

}

}

for (z = 1; z <= N; z++)

{

System.out.println(z);

System.out.println(z*z); 

System.out.println(z*z*z); 

}

for (x = 1; y <= N; x++)

{

    for (y = 1; y <= N; y++)

{

      for (z = 1; z <=N; z++)

      {

System.out.println(x); 

System.out.println(y);

System.out.println(x+y);

System.out.println(x*z);

 }

}

}

 

        What is the complexity (runtime efficiency) of the program by analyzing the runtime grow rate with respect to N? (Using Big O concept and assume N is a very large integer). Give the detailed explanation.
