连续表达式上的函数极值，怎么用C语言的程序编写的代码设计的方式去实现的呢？

Question

Problem Description
Giving N integers, V1, V2,,,,Vn, you should find the biggest value of F.

Input
Each test case contains a single integer N (1<=N<=100). The next line contains N integers, meaning the value of V1, V2....Vn.(1<= Vi <=10^8).The input is terminated by a set starting with N = 0. This set should not be processed.

Output
For each test case, output the biggest value of F you can find on a line.

Sample Input
2
1 2
0

Sample Output
