Fix the signed overflows in the following code so that it calculates the polygon area using the undefined behavior sanitizer. #include #include #include using namespace std; uint64_t area(vector> &points) { int64_t total = 0; size_t n = points.size(); for (unsigned i = 0; i < n; i++) { unsigned j = (i + 1) % n; int x_i = points[i].first; int y_i = points[i].second; int x_j = points[j].first; int y_j = points[j].second; total += (x_i * (y_j - y_i) - y_i * (x_j - x_i)); } total /= 2; return total; }

Question

Fix the signed overflows in the following code so that it calculates the polygon area using the undefined behavior sanitizer.

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

uint64_t area(vector<pair<int, int>> &points) {
int64_t total = 0;
size_t n = points.size();

for (unsigned i = 0; i < n; i++) {
unsigned j = (i + 1) % n;
int x_i = points[i].first;
int y_i = points[i].second;
int x_j = points[j].first;
int y_j = points[j].second;
total += (x_i * (y_j - y_i) - y_i * (x_j - x_i));
}

total /= 2;
return total;
}
