I am unable to figure out why i am getting WA although my solution seems to be correct.
Here is the problem link:CodeChef: Practical coding for everyone
And this is my solution:
#include <bits/stdc++.h>
#include <boost/multiprecision/cpp_int.hpp>
using namespace boost::multiprecision;
using namespace std;
#define int long long
#define ld long double
#define nl ‘\n’
#define pb push_back
#define f(i,n) for(int i=0;i<n;i++)
#define Fast ios_base::sync_with_stdio(0); cin.tie(0); cout.tie(0)
const int M =1e9+7;
void solve()
{
int n;
cin>>n;
vector<vector> v(n+1);
for(int i=1;i<=n-1;i++)
{
int x,y;
cin>>x>>y;
v[x].pb(y);
}
/for(int i=1;i<=n;i++)
{
for(int j=0;j<v[i].size();j++)
{
cout<<v[i][j]<<" ";
}
cout<<nl;
}/
int max=1,d=1,s=0,x=1,j=0,k=1;
for(int i=1;i<=n;i++)
{
s+=v[i].size();
j++;
if(j==x)
{ //cout<<max<<" ";
d++;
if(s>max)
{
max=s;
k=d;
}
x=s;
s=0;
j=0;
}
}
cout<<k<<nl;
}
signed main()
{
Fast;
solve();
return 0;
}
PLEASE look into it.
