$.$ Open mileage$-$array.php and you will see that the code already declares an array that contains the

mileage for $20$ trips. Use a FOR loop to process this array one element at a time as follows: accumulate

the total mileage for all the trips $($$totalMiles$)$; determine the highest value in the array $($$longestTrip$)$;

find the lowest value in the array $($$shortestTrip$)$; count the number of array elements where the

mileage is $100$ or higher $($$longTrips$).$ Also calculate the average of the $20$ mileage values. Use the

sizeof$()$ function to control the loop and to calculate the average. A print statement to print the results is

provided and does not need to be changed but be sure your variable names match those used in the

print statement.
