The following function sums each element in the list:$\{$

int sum $=0$;

for $($int index $=0$; index $$ size; index$++)$

sum $=$ sum $+$ list$[$index$]$;

return sum;

$\}$a$.$ Find the number of operations executed by the function if the value of

size is $10.$

b$.$ Find the number of operations executed by the function if the value of

size is $n.$
