For each sample of code given below, indicate precisely how many times each line

Question

For each sample of code given below, indicate precisely how many times each line runs in terms of the variables given. Sometimes, you will be able to give an exact integral answer, like "10". Other times, your answer will be in terms of n or some other variable or combination of variables. If the snippet of code is a method, you do not have to write the number of times the top line (the method declaration itself) is executed.

You are welcome to submit your responses as text files or scanned images.

5. (Extra credit - 10 pts) for (int i-0 i-; j--) 26. (10 pts) double sum matrix(double matrix[, int m, int n) i //m: num of rows: n: num of cols double sum=0; for (int i-n-1; i>=0; i--) for ( int jan-1; j>=0; j-) { sum = sum + matrix[ U sum = sum + ma t ril i ] [ j ]; return sum;

Explanation / Answer

5) for(int i=0;i<n;i++)     // this statement executes for n times

          for(j=n/2;j>i;j--) // this statement exectues for n/2-i times

                  sum=i+j;    // this statement executes for n/2! times;

   6)

       double sum=0; // for each call one time

      for(int i=m-1;i>=0;i++) // this statement executes for m times

              for(int j=n-1;j>=0;j++) // this statement executes for n times

                    sum=sum+matrix[i][j]; // this statement executes for m*n times

return sum; // for one time
