long double in,avg;
long students[1001],total=0,top,bottom;

#ifndef ONLINE_JUDGE
freopen("C:\\in.txt","r",stdin);
freopen("C:\\out.txt","w",stdout);
#endif


while(scanf("%d",&n)==1)
{
if(n==0)
break;
for(i=0;i<n;i ...

i pointed out... the -ve may lead to runtime error as invalid memory location.. so changed..

if(m<0) m=-m;

still cant solve the runtime error can any 1 help...

hi... can any state why i am getting runtime error watching the following code...i dont have some condition which can result to WA... but can't get why this error is occuring...

midra.... probably the instead of -x in line 2 it will be - x..... i think so...

tahsin..

i am trying to make a knight tour all the position in 64 moves from any position... i used recurvise backtracking... having prob...can some check my code and tell me the mistake...

MY CODE :

int moves[65][2]={0}; //the co-ordinate of each move
int position[9][9]={0}; //the ...

Can't find any clue how to implement a O(n^3) algorithm for this problem.
Can anybody help?

I'm getting WA too. What is the problem with this code? Is there any criticial input that it fails to compute [c]
#include <stdio.h>
#include <string.h>
#define SIZE 500

char word[SIZE],temp[SIZE];
int map[SIZE],l=0;

void arrange(int n){
int i,j;
char temp;
for(i=0;i<n;i++){
for(j=i+1;j<n;j ...

#include<stdio.h>
#include<math.h>
void input();
void calc(int p);
double x1,y1,r1,x2,y2,r2,d;
void main()
{
//freopen("in.txt","r",stdin);
//freopen("out.txt","w",stdout);
input();
}


void calc(int p)
{

double g1,g2,f1,f2,c1,c2,a,b,c,A,B,C,D,X1,X2,Y1,Y2;


g1=-x1; f1=-y1; c1=g1*g1+f1*f1-r1*r1 ...

Thanks! I got ACC now
