I am trying a problem on hacker rank where I am getting the TLE for some cases for following code. So i assumed that may output is coming late but when I run the code in my local compiler using the same test cases,I am getting run time error(i.e. No output at all)

I tried running the debugger but still can’t figure out what is wrong with the code.

```
#include <bits/stdc++.h>
using namespace std;
/*
* Complete the 'journeyToMoon' function below.
*
* The function is expected to return an INTEGER.
* The function accepts following parameters:
* 1. INTEGER n
* 2. 2D_INTEGER_ARRAY astronaut
*/
}
void dfs(int n, vector<vector<int>> adj, vector<int> &visited, int src,int &count)
{
visited[src] = 1;
count++;
for (auto it : adj[src])
{
if (!visited[it])
{
dfs(n, adj, visited, it,count);
}
}
}
int journeyToMoon(int n,vector<vector<int>> adj)
{
// vector<vector<int>> adj(n);
// createAdjacencyList(n, astronaut, adj);
vector<int> visited(n, 0);
vector<int> components;
int count=0;
for (int i = 0; i < n; i++)
{
if (!visited[i])
{
dfs(n, adj, visited, i,count);
components.push_back(count);
count=0;
}
}
int totalPairs=(n*(n-1))/2;
int value;
int check;
for(int i=0;i<components.size();i++)
{
check=components[i];
value=((components[i])*(components[i]-1))/2;
totalPairs-=value;
}
return totalPairs;
}
int main()
{
int n,p;
cin>>n>>p;
vector<vector<int>> adj(n);
for(int i=0;i<p;i++)
{
int u,v;
cin>>u>>v;
adj[u].push_back(v);
adj[v].push_back(u);
}
int result = journeyToMoon(n,adj);
cout << result << "\n";
// fout.close();
return 0;
}
```
