Solution

#include <bits/stdc++.h>

int main() {
    std::ios::sync_with_stdio(false);

    std::vector<int> vec(3, 0);
    std::vector<int> final(3, 0);
    for(int i = 0; i < 3; i++) {
        for(int j = 0; j < 3; j++) {
            std::cin >> vec[j];
        }
        std::sort(vec.begin(), vec.end());
        final[i] = vec[1];
    }

    std::sort(final.begin(), final.end());

    std::cout << final[1] << std::endl;

    return 0;
}
