C++ :

#include <iostream>
#include <cstdio>
using namespace std;
int main()
{ int i,n,a[100];
  scanf("%d",&n);
  for (i=1;i<=n-1;i++) scanf("%d",&a[i]);
  scanf("%d",&a[n]);
  for (i=1;i<=n-1;i++) 
    if (a[i]>a[n]) a[n]=a[i];
  printf("%d",a[n]);
  //system("pause");
  return 0;
}

Python :

# coding=utf-8
k = int(input())
num_list = input().split(' ')
max = int(num_list[0])
for num in num_list:
    if num.strip().isdigit():
        if int(num) > max:
            max = int(num)
print(max)
