Question

Question 4 Suppose that we were to perform a trace of the algorithm that computes the sum of the entries of a matrix (algorithm is provided below) on the matrix [[3, 4], [1, 2], [5, 2]]. What would the value be for the "sum" variable immediately after the i = 2, j = 1 pass of the loop? 1. Input: A matrix A with integer entries denoted by aij, for i = 1, ..., m, and j = 1, ..., n; and positive integers m and n. 2. Initialize: sum := 0. 3. For i starting at 1 up through m. For j starting at 1 up through n. sum := sum + aij (This updates the sum to be the old sum plus the current entry.) Output: sum 17 10 7 8

Suppose that we were to perform a trace of the algorithm that computes the sum of the entries of a matrix (algorithm is provided below) on the matrix
[[3, 4], [1, 2], [5, 2]]. What would the value be for the "sum" variable immediately after the i = 2, j = 1 pass of the loop?

1. Input: A matrix A with integer entries denoted by aij, for i = 1, ..., m, and j = 1, ..., n; and positive integers m and n.
2. Initialize: sum := 0.
3. For i starting at 1 up through m.
For j starting at 1 up through n.
sum := sum + aij (This updates the sum to be the old sum plus the current entry.)
Output: sum
