### 10642 - Can You Solve It?

when I submit it, it says wrong answer

any ideas?

Code: Select all

``````// @JUDGE_ID 51586EH 10642 Java "Can you solve it?"

import java.io.*;
import java.util.*;

class Main
{

{
byte lin[] = new byte [maxLg];
int lg = 0, car = -1;
String line = "";

try
{
while (lg < maxLg)
{
if ((car < 0) || (car == '\n')) break;
lin [lg++] += car;
}
}
catch (IOException e)
{
return (null);
}

if ((car < 0) && (lg ==0)) return (null);
return (new String (lin, 0, lg));
}

public static void main (String[] args)
{
long xa, xb, ya, yb, yc, xc, za, zb, cases, startsubtract=0, loopcnt = 0, moves = 1, casenum = 1;
String input;
StringTokenizer idata;

idata = new StringTokenizer (input);
cases = Integer.parseInt (idata.nextToken());

while (casenum <= cases)
{

idata = new StringTokenizer (input);

xa = Integer.parseInt (idata.nextToken());
ya = Integer.parseInt (idata.nextToken());
xb = Integer.parseInt (idata.nextToken());
yb = Integer.parseInt (idata.nextToken());

xc = xa;
yc = ya;

while (yb != 0)
{
yb--;
xb++;
moves--;
}

zb = xb - 2;

if (xb != 0)
moves = moves + ((xb - 1)*(xb - 1)/2-zb/2 + (2*xb + zb +1));

while (ya != 0)
{
ya--;
xa++;
moves++;
}

za = xa - 2;

if (xa != 0 && za >= 0)
{
moves = moves + 1 - ((xa - 1)*(xa -1)/2-za/2 + (2*xa + zb +1));
//	System.out.println("za > 0");
}

if (za < 0)
{
moves = moves - ((xa - 1)*(xa - 1)/2 + (2*xa +1));
//	System.out.println("za < 0");
}

System.out.println("Case "+casenum+": "+moves);
moves = 1;

casenum++;
}
}
}``````
I know my code is pretty sloppy...but all the tests I ran seemed to generate the right number, but it says wrong answer.

### All your test cases are correct, but what is the answer...

Hi everybody! I tried Arm.Turbo test cases, and everyone is correct, but what should be the answer for this case:
3
0 0 0 0
1 1 1 1
0 1 1 0

### Re: 10642 - Can You Solve It?

It's a mess....shitty thing...the graph is actually inverted. I mean the x-axis labeled is the traditional y-axis and the y-axis is the traditional x-axis. Very easy problem but it took me some time to solve this just because of this inversion thing.

Sorry to say...some of your case is not valid..like case 2.case 6 & case 8.... there can be more..but I didn't check... In those cases we can't go from source to destination... as they are directed... if you draw until these points come,you will see your destination point will come first,then the source point... but it'll never given in judge's input... I just ignored such kinds of inputs & got accepted too....
