11909 - Soya Milk

[Pro.metal]

I am getting WA for this problem. I get the exact ans for the sample I/O.
plz help.

[sohel]

What if the angle is very large?

[zobayer]

large angle with L > H

Nice problem .

Sample I/0:

Code: Select all

89 5 10 80

output:

Code: Select all

44.082 mL

I am confused about the process of solving. Can anyone discuss about that?

[shaon_cse_cu08]

Suparb problem...!! for the condition where l>h && Angle is very large... we have to check whether the surface of the milk is in between 'h' or not...that is if (l*tan(ang))>h
then only the portion of milk that is Volume of the Triangle is the result....

I solved this in my first try. I must agree with everyone else, this is a really great problem. Please don't underestimate the problem. Although the problem description says that it may not perfectly match the real-life situation, I am going to advice you to visualize this as a real-life situation. Here are some test cases if you get WA.

2 8 9 85
17 32 87 5
17 9 87 82

Output should be:
28.346 mL
46923.452 mL
4786.891 mL

respectively

Hello all I'm getting WA. But Why , though I test the cases 9 6 19 20 & 89 5 10 80, have any more critical input? or let see the code mine below:

#include <algorithm>
#include <cstdio>
#include <cmath>
#include <cstring>
#include <deque>
#include <fstream>
#include <iostream>

#include <set>
#include <stack>
#include <string>
#include <vector>
#include<stdio.h>
#include<stdlib.h>
#define PI 4*atan(1)

int main()
{
	float l, w, h, th, vol, tvol, v, o, result, area, res;
	while(scanf("%f%f%f%f", &l,&w, &h, &th)==4)
	{
        if(l<=h)
        {
            result=cos (th*PI/180);
            o=l/result;
            v=sqrt(o*o-l*l);
            vol=.5*l*v*w;
            tvol=l*w*h;
            res=tvol-vol;
        }
        else if(l>h)
        {
            result=tan((90-th)*PI/180);
            v=h*result;
            vol=.5*v*h*w;
            res=vol;
        }
        printf("%.3f mL\n",res);
    }
	return 0;
}

Try using double instead of float.

[esharif]

For double the problem gives o/p 0.000 but for long double gives correct answer at my compiler but UVA gives me WA. What can I do now?
