Question $1$:

Assume that the above function is defined in the current directory. The following code is then run in the Command Window:

$```$

arr $=[20$; $31$; $25$; $48]$;

$[$new$1,$max$1]=$ bestSum$($arr$)$

$```$

After the function is run, what will be the values of new$1$ and max$1?$

Question $2$:

Using the same input given in question $1,$ how many TOTAL times will the for loop on lines $6-8$ run?

Question $3$:

Suppose that Line $10$ is uncommented. Does the for loop now operate different? If you believe it operates differently, what will the values of temp and newArr be once the code reaches line $12.($In other words, after the loop from $4-11$ is done$)```$

function $[$newArr$,$ maxSum$]=$ bestSum$($arr$)$

$[$r$,$c$]=$ size$($arr$)$;

newArr $=[]$;

fori $=1$:c

temp $=0$;

for j $=1$:r

temp $=$ temp $+$ arr$($j$,$ i$)$;

end

newArr $=[$newArr temp$]$;

$\%$ i $=$ i $+1$;

end

ind $=2$;

maxSum $=$ newArr$(1)$;

while ind length$($newArr$)$

if newArr$($ind$)>$ maxSum

maxSum $=$ newArr$($ind$)$;

end

ind $=$ ind $+1$;

end

end

$```$
