can someone tell why am i getting WA?
I have checked all the test cases provided by the Electronic board. I cannot uderstand also wot wud b the calculation for a=180;
#include<stdio.h>
#include<math.h>
#include<string.h>
#define MAX 5
//#define pi 3.14159265358979323846
#define R 6440
int main(void)
{
double s,a ;
char str[MAX];
double rad, arc, cord, pi;
//freopen("10221.txt","r",stdin);
pi= acos(-1);
while((scanf("%lf%lf%s",&s,&a,str))==3)
{
if(a>180 && !( strcmp(str,"deg")) )
{
a=360-a;
}
if(!(strcmp(str,"deg")))
{
rad=(pi*a)/180;
}
else
{
a=a/60;
rad=(pi*a)/180;
}
/*if(a==180) ///is it ok?????????
{
arc=(R+s)*rad;
cord= 2.0*R+s;
}*/
if (a<=180)
{
arc = (R+s)*rad;
cord=( (R+s)*sin(a/(180/pi)) )/sin((0.5*(180-a))/(180/pi) );
}
printf("%.6lf %.6lf\n",arc, cord);
}
return 0;
}
thanx in advance!

well u had made an silly mistake
....
U should consider a = 180 & when a != 180..
By the way the formula for chord is
Chord_distance=2*radius*sin(angle/2)
for when a != 180
and Chord_distance=2*radius for when a = 180
am thinking r u calculation ur radius as
radius = R or radius = R+s -----> ur mistake

All test case has passed but still WA!
where is the problem?
Code: Select all
#include <cstdio>
#include <cmath>
#include <cstring>
#include <algorithm>
#define R 6440
#define PI 2*acos(0.0)
using namespace std;
int main(){
//freopen("in.txt","rt",stdin);
int s,a;
double arcDistance,cordDistance,sinA,sinB;
char str[100];
while(gets(str))
{
sscanf(str,"%d %d %s",&s,&a,str);
if(strstr(str,"min"))
a /= 60;
s = s + R;
arcDistance = s * a * PI/180;
sinA = sin(a*PI/180);
sinB = sin((180 - a)*PI/360);
if(a != 180)
cordDistance = s * sinA / sinB;
else
cordDistance = 2*s;
printf("%.6lf %.6lf\n",fabs(arcDistance),fabs(cordDistance));
}
return 0;
}

Please say, what is my wrong? i am so suppressed.
Code: Select all
#include<stdio.h>
#include<math.h>
int main(){
double s,a,pi,chord,rad,arc;
char ch[6];
pi=2*acos(0.0);
while((scanf("%lf %lf %s",&s, &a, &ch))==3){
if(ch[0]=='m')
a=a/60;
if(a>180)
a=a-180;
rad=pi*a/180;
if(a==180){
arc=pi*(s+6440);
chord=2*(s+6440);
}
else{
chord=2*(s+6440)*sin(rad/2);
arc=rad*(s+6440);
}
printf("%.6lf %.6lf\n",arc,chord);
}
return 0;
}
Quickly. please.
wa pls help

why wrong answer
Code: Select all

#include<math.h>
#include<string.h>
#define pi 3.1415926535897932384626433832795
int main()
{
//freopen("10221.txt","r",stdin);
int s;
char a[10];
long double ans,temp,len,ac,deg;
while((scanf("%d %Lf %s",&s,°,&a)==3)){
if(!strcmp(a,"min"))
ans=deg/60;
else
ans=deg;
if(ans>180)
ans-360-ans;
ans=(pi*ans)/180;
ac=6440+s;
temp=(ac)*ans;
len=2*ac*ac*cos(ans);
len=(ac*ac)+(ac*ac)-len;
len=sqrt(len);
printf("%.6Lf %.6Lf\n",temp,len);
}
return 0;
}

@calicratis19 thank you very much. at last worked by reducing calculation.
More variable although with right calculation surly will get wrong answer.
@asif_khan_ak_07 try to reduce your variables. and don't forget to edit this part.
more info in my pm. keep solving

Remember, if the angle is greater than 180.0(in degrees), then calculate with 360 - angle size
. Just do the following thing to avoid complexity, take s and a as double and the angle unit as string(Remember to eliminate buffer). Then if str[0] == 'm', angle(a) = a / 60.0. I got AC without adding 1e-8 or stuff like that. Good luck

I am getting run time error.But I think my code is ok.
My code:
#include<stdio.h>
#include<math.h>
#define pi 2*acos(0)
int main()
{
// double pi=;
double s,angel,rad,radius,ans1,ans2;
char array[5];
while(scanf("%lf%lf%S",&s,&angel,&array)==3)
{
if(angel>180)
angel=360-angel;
//printf("%d\n",angel);
if(array[0]=='m')
angel=angel/60;
rad=(pi/180)*angel;
//printf("%lf\n",rad);
radius=s+6440;
ans1=rad*radius;
ans2=2*radius*sin(rad/2.0);
printf("%0.6lf %0.6lf\n",ans1,ans2);
}
return 0;
}

Change line 10 to:
while(scanf("%lf%lf%s",&s,&angel,array)==3)
