whats problem on test 3??
что за проблема на 3 тесте??

Yep
Why my code get WA3?
#define _CRT_SECURE_NO_WARNINGS
#include <iostream>
#include <vector>
#include <cstring>
#include <set>
#include <map>
#include <cmath>
#include <algorithm>
using namespace std;

#define ll long long

const ll nmax = 100005;
const ll inf = 1234567890123;

ll A, B, C;
ll X, Y, Z;

int main()
{
   cin>>A>>B>>C;
   cin>>X>>Y>>Z;

    if(Z > C)
        cout<<"There are no miracles in life";
    else
    {
        ll ess = (ll)0;
        if(X > A) ess += X - A;
        if(Y > B) ess += Y - B;
        if(C - Z >= ess)
            cout<<"It is a kind of magic";
        else
            cout<<"There are no miracles in life";
    }


   return 0;
}


or more simple

#define _CRT_SECURE_NO_WARNINGS
#include <iostream>
#include <vector>
#include <cstring>
#include <set>
#include <map>
#include <cmath>
#include <algorithm>
using namespace std;

#define ll long long

const ll nmax = 100005;
const ll inf = 1234567890123;

ll A, B, C;
ll X, Y, Z;

int main()
{
   cin>>A>>B>>C;
   cin>>X>>Y>>Z;

   if(X > A)
        C -= (X - A);
   if(Y > B)
        C -= (Y - B);
   if(Z <= C)
        cout<<"It is a kind of magic";
   else
        cout<<"There are no miracles in life";

   return 0;
}

try
3 3 2
5 0 3
answer
YES
