described
output an integer sequence number is not the same as the maximum sum of the numbers.

Input
Input into two lines:
a first behavior N (N is the number of the next number, N <= 100);
a second behavior of N integers, and the number to a number between separate spaces, each integer is the range -1000,000 to 1000,000.
Output
the output of the maximum number and the remaining digits of the number N is removed.
Sample input
