[kangroo]

hi everybody,

is the test case provided by "helloneo" 1 0 2 0 a valid one ??
in the problem desc its given tat 1 <= X1,Y1,X2,Y2 <= 8...
but here Y1 = 0 and Y2 = 0...
how is it posible ???

Maybe there is no case like that..

[kangroo]

I've no idea where I've gone wrong in the logic..getting WA in Queen;please,can anyone help me?

Code: Select all

#include<stdio.h>
int absolute(int x)
{
    if(x<0) return x*(-1);
    else return x;
}
int main()
{
    int x1,y1,x2,y2,move;
    while(1)
    {
            scanf("%d%d%d%d",&x1,&y1,&x2,&y2);
            if((x1==0) && (y1==0) && (x2==0) && (y2==0)) break;
            if((x1==x2) && (y1==y2)) move=0;
            else if((x1==x2) && (y1=!y2)) move =1;
            else if((x1!=x2) && (y1==y2)) move=1;
            else if((x1!=x2) && (y1!=y2))
            {
                 if(absolute(x1-x2)==absolute(y1-y2)) move=1;
                 else move=2;
                 }
            printf("%d\n",move);
            }
    return 0;
}

[sohel]

In this condition

else if((x1==x2) && (y1=!y2)) move =1;

shouldn't it be y1!=y2 ?

!= and =! aren't the same thing.

[engnaruto]

i want to know what's wrong with my code

Code: Select all

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {

		Scanner input = new Scanner(System.in);
		while (input.hasNext()) {

			int x1 = input.nextInt();
			int y1 = input.nextInt();
			int x2 = input.nextInt();
			int y2 = input.nextInt();

			if (x1 > 8 || x1 < 0 || x2 > 8 || x2 < 0 || y1 > 8 || y1 < 0
					|| y2 > 8 || y2 < 0) {
				System.exit(0);
			} else if (x1 == 0 && x2 == 0 && y1 == 0 && y2 == 0) {

				System.exit(0);

			} else if ((Math.abs(x1 - x2) == Math.abs(y1 - y2))
					|| ((x1 - x2) == 0) || ((y1 - y2) == 0)) {

				System.out.println(1);

			} else if ((x1 == x2) && (y1 == y2)) {

				System.out.println(0);

			} else {
				System.out.println(2);

			}

		}

	}
}

It doesn't match the sample I/O.

[brianfry713]

That is AC code

[uDebug]

Here's some input / output that I found useful during testing / debugging.

Input:

Code: Select all

1 8 8 8
1 5 6 1
3 7 2 8
5 5 8 8
8 3 8 3
8 3 6 1
1 3 3 1
7 8 7 1
