Code: Select all

#define PI 0.01745329251994329914588889

please help.im getting wa. heres my code.

Code: Select all

#include<iostream>
#include<string.h>
#include<math.h>
#define pi 2*acos(0.0)/180
using namespace std;

int main()
{
	long cases,n;
	double x,y,k;
	double thita;
	double f,g;
	long F,G;

	while(scanf("%ld",&cases)==1)
	{
		while(cases--)
		{
			x=0,y=0;
			thita=90;
			scanf("%ld",&n);
			while(n--)
			{
				
				char ins[10];
				double to;
				scanf("%s %lf",ins,&to);
				
				if(strcmp(ins,"fd")==0)
				{
					k=thita*pi;	
					x+=to*cos(k);
					y+=to*sin(k);
				}
				else if(strcmp(ins,"lt")==0)
					thita+=to;
				
				else if(strcmp(ins,"rt")==0)
					thita-=to;
			}
			
			f=floor(sqrt(x*x+y*y));
			g=ceil(sqrt(x*x+y*y));
			F=long(f);
			G=long(g);
			if(((fabs(sqrt(x*x+y*y)-f))>(fabs(sqrt(x*x+y*y)-g))))
				printf("%ld\n",G);
			else
				printf("%ld\n",F);
			

		}
		
	}
	
	return 0;

@Nahiyan Kamal

to convert thita into radian,
thita = thita * pi / 180;
pi = acos(-1.0)

thita is always between 0 to 360 degree
so take care of it, if it goes beyond limit

try this input :

Code: Select all

3
5
lf 60
fd 20
rt 30
fd 50
rt 45
3
fd 20
lf 15
fd 17
6
fd 50
lf 90
fd 50
lf 90
fd 50
lf 90

Code: Select all

output :
25
22
120
I took an IQ test .. and the results were negative ! :(

The above output is WRONG.

Correct output :

Code: Select all

68
37
50
Even the input is WRONG.
lf should be replaced by lt.

"bk" just means move back, the turtle would not turn its head back.
