I don’t know why I’m getting a wrong answer for “The Morning Commute”. It works on all of the examples they provided. Please help me!

The Problem: http://www.codechef.com/problems/COMMUTE

My Code:

```
#include <iostream>
using namespace std;int main() {
int t, n;
cin >> t;
while (t--){
cin >> n;
int ** schedule;
schedule = new int*[n];
for (int a = 0; a < n; a++){
schedule[a] = new int[3];
cin >> schedule[a][0] >> schedule[a][1] >> schedule[a][2];
}
int current_time, total_time;
current_time = 0;
total_time = 0;
for (int a = 0; a < n; a++){
if (current_time < schedule[a][0]){
total_time += schedule[a][0] - current_time;
current_time = schedule[a][0];
}
else {
if (current_time%schedule[a][2] != 0){
total_time += schedule[a][2] - (current_time % schedule[a][2]);
current_time += schedule[a][2] - (current_time % schedule[a][2]);
}
}
total_time += schedule[a][1];
current_time += schedule[a][1];
}
cout << total_time << endl;
}
return 0;
```
