#include<iostream>
#include<vector>
#include<algorithm>
using namespace std;

long long maxSum, minSum;

int main() {   
    int n;
    cin >> n;

    vector<int>B(n);
    for (auto& it : B)
    {
        cin >> it;
        maxSum += it;
    }

    auto last = unique(B.begin(), B.end());
    B.erase(last, B.end());
    for (auto& it : B) {
        minSum += it;
    }

    cout << maxSum << endl << minSum;
    return 0;
