Question 9

Time: 00:00:00
Ravi and Rupali are asked to write a program to sum the rows of 2X2 matrices stored in the array A.?
Ravi writes the following code (Code A):
```for n = 0 to 1
sumRow1[n] = A[n][1] + A[n][2]
end
Rupali writes the following code (Code B):
sumRow1[0] = A[0][1] + A[0][2]
sumRow1[1] = A[1][1] + A[1][2]

```

Code A will execute faster than Code B

Code A will execute faster than Code B
