12502 - Three Families

[xplosive]

Why i am getting runtime error...? I tried for four time but same result rte...

Code: Select all

#include <iostream>
#include <cstdio>

using namespace std;

int main()
{

    //freopen("uvainput.txt", "r", stdin);
    //freopen("uvaoutput.txt", "w", stdout);

    int t,tt;
    scanf("%d",&tt);

    int x,y,z,ave,over,r;

    for(t=0; t<tt; t++)
    {
        scanf("%d%d%d",&x,&y,&z);

        ave=(x+y)/3;
        over = x-ave;
        r= z*over/ave;

        printf("%d\n",r);


    }


    return 0;
}

Try input:

Code: Select all

1
1 1 1

[mahade hasan]

Try input:

Code: Select all

1
1 1 1

out put will be floating
what will be the answer

[brianfry713]

0

Sir, I think the AC output is 1.

[brianfry713]

Either 1 or 0 would make sense. There won't be a case like that in the judge's input.

got WA.
can't find error.

plz help.

removed after AC

Does't Match simple I/O

Code: Select all

Input:
3
6 7 50
3 9 120
11 11 987
your code says:
23

Beware this is one of those annoyingly clever problems on UVa. The problem statement is confusing (on purpose) - and then if you use floating point numbers you'll likely end up getting a WA.

In regards to the problem statement: What's not made very clear is that the families do not get paid for their own share of the work. Family C is paying Family A and B only for work that Family C did not do.

On the floating point front, think a little outside the box. Maybe a change in time units, perhaps.

I got accepted using only double for variables.

I am getting WA with my code. Whats wrong?

Code: Select all

Accepted !

[brianfry713]

Try solving it without using floating-point numbers.

[Shahidul.CSE]

I can't figure out the trick to solve using int .
