Did it pass samples on CodeChef IDE or just your computer? Either way, it’s probably the multitests causing sum to have some garbage value.
on my computer as well as on ideone…
probably were the multitests
what about CodeChef IDE
thanks got it. it was the multitests causing it to go haywire
import java.io.;
import java.lang.;
import java.util.Scanner;
public class Main
{
public static void main(String args[])
{
Scanner in=new Scanner(System.in);
int t,p;
t=in.nextInt();
for(int i=t;i>0;i–)
{
int a[]=new int[5];
for(int j=0;j<5;j++)
{
a[j]=in.nextInt();
}
p=in.nextInt();
long sum=0,s=0;
for(int j=0;j<5;j++)
{
sum=sum+a[j];
}
if((sum*p) > 120)
System.out.println(“YES”);
else
System.out.println(“NO”);
}
}
}
same method still getting WA
t=int(input())
for f in range(t):
l=[int(x) for x in input().split()]
sums=0
for i in range(5):
sums+=l[i]
sums=sums*l[5]
if(sums>144):
print(“YES”)
else:
print(“NO”)
Pls someone tell why this is not working
t=int(input())
for f in range(t):
l=[int(x) for x in input().split()]
sums=0
for i in range(5):
sums+=l[i]
sums=sums*l[5]
if(sums>144):
print(“YES”)
else:
print(“NO”)
Firstly, a workweek here is 5 days. So sum need to be greater than 120 only rather than 144.
Secondly, the output might be case sensitive.
@admin @everyone
I have done a similar approach and compared maximum work that can be done per day * 5 versus sum.
Why was this a WA as I have just transferred { Editorial : p * sum > 120 } to { sum > ( 120 / p ) }
Full code can be found here : CodeChef: Practical coding for everyone
int main()
{
tc
{
lli a[5] = {0}, p = 1;
aip(a, 5);
lli sum = 0;
rep(i, 0, 5)
sum += a[i];
cin >> p;
lli max = (24 / p) * 5;
if (max >= sum)
cout << "No\n";
else
cout << "Yes\n";
}
return 0;
}
By dividing the no of available hours from each day with p, you are discarding the fractional value which might affect the answer.
Sample test run but still getting WA
public static void main(String[] args) throws java.lang.Exception {
List<Integer> numbers = new ArrayList<>(5);
Scanner sc = new Scanner(System.in);
IntStream.range(0, 5).forEach(x -> {
numbers.add(x, sc.nextInt());
});
List<Integer> totalWorkingHours = new ArrayList<>();
int pHour = sc.nextInt();
numbers.forEach(workHour -> {
int totalHourPerDay = workHour*pHour;
totalWorkingHours.add(totalHourPerDay);
});
if (new Codechef().sumOfWeekdayHours(totalWorkingHours) <= 120) {
System.out.println("No");
} else {
System.out.println("Yes");
}
}
public int sumOfWeekdayHours(List<Integer> totalWorkingHours) {
int sum = 0;
for (int weekdayHour : totalWorkingHours) {
sum = sum + weekdayHour;
}
return sum;
}Oh yep it’s correct. Thanks bro ! What a silly mistake 
anyways learnt something
can anyone please say what is wrong in this code please reply
#include

The same error what I did during contest.Print “Yes” and “No” but your code is printing "YES and “NO”.
Whats wrong with my code?
#include <bits/stdc++.h>
#include
using namespace std;
int main() {
// your code goes here
int t;cin>>t;
while(t–)
{
int arr[5]={0};
for(int i=0;i<5;i++)
{
cin>>arr[i];
}
int p;cin>>p; int sum=0;
for(int i=0;i<5;i++)
{
arr[i]=arr[i]*p;
sum+=arr[i];
}
if(sum/24<=5)
{
cout<<"No"<<endl;
}
else
{
cout<<"Yes"<<endl;
}
}
return 0;
}
If sum is between 120 and 144. Since we are having integer division it will be 5 only, Hence , Condition in if will be true while it should be false.
why my code is showing error…very frustating …
#include<bits/stdc++.h>
using namespace std;
typedef long long ll;
int main()
{
ll t;
cin>>t;
while(t–)
{
ll a[5],i,p,sum=0;
for( i=0;i<5;i++)
{
cin>>a[i];
sum+=a[i];}
cin>>p;
if(sum*p >5*24 )
cout<<"YES\n";
else
cout<<"NO\n";
}
return 0;
}
It should be while(t–) instead of (t-)
