#include <iostream>
using namespace std;

int main(){
  
  int N;
  int A[100000];
  
  cin >> N;
  for (int i = 0; i < N; i++) {
    cin >> A[i];
  }
  
  bool can = true;
  
  int sum = 0;
  for (int i = 0; i<N; i++){
    sum += A[i];
  }
  if (sum%2 != 0) can = false;
  
  if (can) cout << "YES" << endl;
  else cout << "NO" << endl; 
  
  return 0;
}
