$8\mathrm{.}9\mathrm{.}1$: Find $2$D array max and min.

Write a loop to iterate from $0$ to the last row of milesTracker. Within each row, use a nested loop to iterate from $0$ to the last column of milesTracker.

Within the nested loop, if an element is greater than maxMiles, assign maxMiles with the value of the element. Similarly, if an element is less than minMiles, assign minMiles with the value of the element.

Ex: If the input is:

$-10203040$

the output is:

Min miles: $-10$

Max miles: $40$
