#include <iostream>
using namespace std;

int main() {
unsigned long long n,a,b,c,s;
int i;
unsigned long long  x[100001];
memset(x,0,sizeof(x));
cin>>n;
for (i=1;i<=n+1;i++)
{
cin>>a>>b>>c;
x[a]=x[a]+c;
x[b+1]=x[b+1]-c;
};s=0;
for (i=1;i<=n;i++)
{
s=s+x[i];
if (i==n) cout<<s<<endl; else
cout<<s<<" ";
}
};

tried to make this code faster, but seems its imposible

just use vector
