Modify the above code to compute the sum of a $1000$ x $1000$ array by spliting up the $4$ tasks in a different way. For example, you could have task$1$ sum the first $1/4$ of rows, task$2$ sum the second $1/4$ of rows, task$3$ sum the third $1/4$ of rows and task$4$ sum the last $1/4$ of rows.$$ Submit your modified code via Canvas with your name$/$date$/$e$-$mail, an overview comment and program comments describing your approach for credit. $$

Hint: $$You don't have to be that creative. $$ Try starting at different points rather than having everyone start at the beginning.
