Ravi and Rupali are asked to write a program to sum the rows of 2X2 matrices stored in the array A.
\nRavi writes the following code (Code A):<\/p>\n

 for n = 0 to 1 \r\n sumRow1[n] = A[n][1] + A[n][2]\r\n end<\/pre>\n
Rupali writes the following code (Code B):<\/p>\n
sumRow1[0] = A[0][1] + A[0][2] \r\nsumRow1[1] = A[1][1] + A[1][2]<\/pre>\n
Comment upon these codes (Assume no loop unrolling done by compiler) ?<\/p>\n
