Problem Link

I had pre-calculated the factors p1, p2 and was using dfs to allocate p1 and p2 alternatively.

```
#include<bits/stdc++.h>
using namespace std;
typedef unsigned long long int ull;
typedef long long ll;
constexpr ull a1 = 1482918936932394962, a2 = 1554749829221870235;
vector<int> G[105];
vector<ull> value(105);
void dfs(int source = 1, int prev = -1, int i = 0)
{
if (i == 0)
value[source] = a1;
else
value[source] = a2;
for (auto &x : G[source])
{
if (x != prev)
dfs(x, source, i ^ 1);
}
}
int main()
{
ios_base::sync_with_stdio(0);
cin.tie(0);
cout.tie(0);
register int test, i, j;
cin >> test;
int n, x, y;
while (test--)
{
cin >> n;
for (i = 0; i < n; i++)
{
cin >> x >> y;
G[x].push_back(y);
G[y].push_back(x);
}
dfs();
for (i = 1; i <= n; i++)
{
cout << value[i] << ' ';
}
cout << "\n";
for(i = 1; i <= n; i++)
G[i].clear();
}
return 0;
}
```

I even tried dfs using visited array, that’s also giving TLE
