Hey guys, I passed all test cases but two. Cant seem to figure out whats wrong with my solution. Am I missing any corner cases?

#include <bits/stdc++.h>
using namespace std;
int main() {
  int N; cin >> N;
  int* firstData = new int[N];
  int* secondData = new int[N];
  int minIndex = 0; int min = 2147483647; int sum = 0;
  for (int i = 0; i < N; i++) {
    int one, two, three;
    cin >> one >> two >> three;
    firstData[i] = one;
    secondData[i] = two + three;
    int cur = two + three;
    if (cur < min) {
      min = cur;
      minIndex = i;
    }
    sum += one;
  }
  sum += secondData[minIndex];
