Sum of Digits – Largest Integer

The program must accept N integers as the input. The program must print the sum of the digits of the largest integer among the N integers as the output.

Boundary Condition(s):
1 <= N <= 100
1 <= Each Integer Value <= 1000

Input Format:
The first line contains the integer N.
The second line contains N integers separated by space(s).

Output Format:
The first line contains the sum of the digits of the largest integer among N integers.

Example Input/Output 1:
Input:
6
98 74 85 23 58 21

Output:
17

Explanation:
The largest integer is 98.
So the sum of the digits of 98 is 17 (9 + 8).
Hence the output is 17

Example Input/Output 2:
Input:
9
401 884 8 203 123 950 475 520 193

Output:
14
