#include <vector>
using namespace std;
int main() {
ifstream input("input.txt");
vector<int> lhs, rhs;
int left, right;
while (input >> left >> right) {
lhs.push_back(left);
rhs.push_back(right);
}
unordered_map<int, int> rhsCounts;
for (int num : rhs) {
rhsCounts[num]++;
}
long long score = 0;
for (int num : lhs) {
score += (long long)num * rhsCounts[num];
}
cout << score;
}
