Returning a pair

Lab C++ Intermediate 20 points

Write pair<int, int> minMax(const vector<int> &v). Read a list and print its minimum and maximum using structured bindings: auto [lo, hi] = minMax(v);

Input

Line 1: n. Line 2: n integers.

Output

One line: min max

Example

Input

5
3 9 -2 7 1

Output

-2 9

C++

Hints

return {lo, hi}; builds the pair.

Structured bindings (C++17) unpack it into two names.

Solution explanation

pair and tuple are the C++ way to return several values.

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

pair<int, int> minMax(const vector<int> &v) {
    int lo = v[0], hi = v[0];
    for (int x : v) {
        if (x < lo) lo = x;
        if (x > hi) hi = x;
    }
    return {lo, hi};
}

int main() {
    int n;
    cin >> n;
    vector<int> v(n);
    for (int &x : v) cin >> x;
    auto [lo, hi] = minMax(v);
    cout << lo << " " << hi << "\n";
    return 0;
}
