Question $2$

Given an $nm$ matrix, $a,$ where each $a(i,j)$ is the value of the cell at the intersection of row i and column $j,$ create another $nm$ matrix, $b,$ using the following algorithm to set the values of each $b(x,y)$ with zerobased indexing:

$s=$

for

for

$s=s+a(i,j)$

$\}$

$\}$

$b(x,y)=s$

Note that the algorithm sets just one $b(x,y)$ per execution and that $0y$

$If$ matrix $ais$:
