Posted: Thu Nov 05, 2009 2:57 pm
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;
}
.................................................
}
}

whats wrong with that?

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

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

why WA?? i got AC with the same code once i submitted 1st time.

Code: Select all

``````#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++;
}

}

Input:

Code: Select all

``````3 6 1 6
