Where Mycode going wrong it is showing WA as well as TLE.
here is my code:
#include <bits/stdc++.h>
using namespace std;
int main() {
int t;
int x,y,n,k,ans=0;
cin>>t;
while(t–){
ans=0;
cin>>x>>y>>n>>k;
int page[n],cost[n];
//cout<<n<<endl;
for(int i=0;i<n;i++){
cin>>page[i]>>cost[i];
}
for(int i=0;i<n;i++){
if((page[i]>=(x-y))&&(cost[i]<=k)){
ans=1;
break;
}
}
if(ans==1)
cout<<“LuckyChef”<<endl;
else
cout<<“UnluckyChef”<<endl;
}
return 0;
}
You’re reading the input in the wrong order: look at the Input section of the Problem statement more carefully 
T=int(input())
for i in range(T):
X,Y,K,N=map(int,input().split())
p=[]
c=[]
flag=1
for j in range(N):
p,c=map(int,input().split())
if(c<=K and p+Y>=X):
flag=0
if(flag==0):
print('LuckyChef')
else:
print('UnluckyChef') public static void main (String[] args) throws java.lang.Exception
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int t = Integer.parseInt(br.readLine());
String mainInput[];
int no_of_pages_required;
int no_of_pages_left;
int money;
int no_of_notebooks;
String notebook_details[];
int pages;
int price;
boolean flag;
for(int i = 0; i<t; i++) {
flag = true;
//assignment of inputs
mainInput = br.readLine().split("\\s+");
no_of_pages_required = Integer.parseInt(mainInput[0]);
no_of_pages_left = Integer.parseInt(mainInput[1]);
money = Integer.parseInt(mainInput[2]);
no_of_notebooks = Integer.parseInt(mainInput[3]);
for(int j = 0; j<no_of_notebooks; j++) {
//assignment of notebook_mdetails
notebook_details = br.readLine().split(" ");
pages = Integer.parseInt(notebook_details[0]);
price = Integer.parseInt(notebook_details[1]);
if(pages >= no_of_pages_required - no_of_pages_left && price <= money) {
System.out.println("LuckyChef");
flag = false;
break;
}
}
if(flag)
System.out.println("UnluckyChef");
}
}
I am getting Runtime error - NZEC in this. Can’t get it to working 
Alright. Checking into it right away.
I’ve just edited that post as the testcase contained some extra whitespace that caused your solution to choke, so make sure you’re using the updated testcase to debug 
Got it working. I really need to start focusing on the little things. Thanks for the help!
Exact replica for your Python 2 code in Python 3 does not work. I mean it gives runtime error. Please help!
T = int(input())
for i in range(T):
X,Y,K,N = map(int, input().split(’ ‘))
books = []
for k in range(N):
p,c = map(int, input().split(’ '))
books.append((p,c))
for p,c in books:
if p>=(X-Y) and c<=K:
print(‘LuckyChef’)
break
else:
print(‘UnluckyChef’)
Figured out the solution myself.
I think there was extra whitespace in test cases…so added input().strip().split(’ ') and it is working now!!
#include
using namespace std;
int main() {
int i,t,x,y,k,n,p,c,j=0;
cin>>t;
for(int i=0;i<t;i++)
{cin>>x>>y>>k>>n;
bool found=false;
for(int i=0;i<n;i++)
{cin>>p>>c;
if(p>=x-y&&c<=k)
{found=true;
break;
}}
cout<<(found?“LuckyChef”:“UnluckyChef”)<<endl;}
return 0;
}
Please help me.
When i run the program it runs successfully but on submission shows wrong answer.
Can somebody please point out the mistakes.
Please either format your code or (better!) link to your submission - the forum software has mangled it and it won’t compile!
Edit:
While we’re waiting - make sure your code gets the correct answer for this testcase.
Very well organized and over simplified tutorial ! Exactly what a newbie like me needs !
GREAT WORK!

This solution is giving runtime error because of break statement in the if block. Please tell me the reason behind it.
Try with this testcase:
and all should become clear
#include
using namespace std;
int main() {
long long t,poet,chefpage,chefK,n,pageN,costN;
cin>>t;
while(t–){
bool f=false;
cin>>poet>>chefpage>>chefK>>n;
while(n–){
cin>>pageN>>costN;
if(pageN>=poet-chefpage && costN<=chefK){
f=!f;
break;
}
}
if(f){
cout<<“LuckyChef”<<endl;
}else{
cout<<“UnluckyChef”<<endl;
}
}
return 0;
}
The only difference I see in the array for cost and pages. int P[111111];
int C[111111]; how does This give the correct answer please explain if you get to know.
