I have got WA for this problem.Is there any trick with that problem?

can anyone please send some spical input for this problem?

my algorithom()
{
while(scanf("%ld",&n)!=EOF)
{
if(n==1)
{
print desired result;
}

else if(n==1)
{
print desired result;
}

else if(n==1)
{
print desired result;
}

Well, why are your conditional statements only if n == 1?

@s.islam
check this code...and make the correction from your code:-:
read (c);
if(c==0)
break;
if(c==1)
read (u,v,t);
a=(v-u)/t;
s=(v*v-u*u)/(2*a);
if(c==2)
read(u,v,a);
t=(v-u)/a;
s=(v*v-u*u)/(2*a);
if(c==3)
read(u,a,s);
v=sqrt((u*u+2*a*s));
t=(v-u)/a;
else if(c==4)
read(v,a,s);
u=sqrt((v*v-2*a*s));
t=(v-u)/a;
Hope you will get it........

#include<stdio.h>
#include<math.h>
#include<iostream>
using namespace std;

int main() 
{
 	int n;
 	long double a, b, c;
 	int i = 1;
 	while ((scanf("%d %lf %lf %lf",&n,&a,&b,&c))==4) 
	{
 		if (n == 1) 
		{
 			long double res2 = (b-a)/c;
 			long double res1 = (a*c) + (0.5*res2*c*c);
 			printf("Case %d: %0.3lf %0.3lf\n", i, res1, res2);
 		}
 		if (n == 2) 
		{
 			long double res2 = (b-a)/c;
 			long double res1 = (a*res2) + (0.5*c*res2*res2);
 			printf("Case %d: %0.3lf %0.3lf\n", i, res1, res2);
 		}
 		if (n == 3) 
		{
 			long double res1 = sqrt(a*a + 2*b*c);
 			long double res2 = (res1-a)/b;
 			printf("Case %d: %0.3lf %0.3lf\n", i, res1, res2);
 		}
 		if (n == 4) 
		{
 			long double res1 = sqrt(a*a - 2*b*c);
 			long double res2 = (a-res1)/b;
 			printf("Case %d: %0.3lf %0.3lf\n", i, res1, res2);
 		}
 		i++;
 	}
