Yes, i use the command prompt.

I have a problem about java's complier.

i complier a simple program. "Hello World!" in my new computer. and it cost about 20 secs.

My java version is J2SDK1.4.0_02.

i try Windows XP and Windows 2000 professional , and i get the same result.

i hope anyone can tell me how to solve. thx.

ywLiu ...

i already tried to BF solution before DP solution.
and sample test is all right.
0.20 4
2.00 293
50.00 513269191

but it also got WA.

so......I really don't know where the problem.

it's my code using BF solution.

[cpp]
#include<iostream>
#include<string>
using namespace std;

long value ...

I use Dynamic Programming.....and sample test is all right.
0.20 4
2.00 293
50.00 513269191

but i got WA from beginning to end.

someone can tell me why i got WA.

[cpp]
#include<iostream>
#include<string>
using namespace std;

long value,count;
long m[10][1001];
long v[10]={1,2,4,10,20,40,100 ...

but i have a new thorny problem now.

during solving program, i always send solved program. and get WA..

and i think my program is no problem. and i have some test data.

and all result is right . but always get WA.

i already have four programs with problem like above description

it is respective ...

oh....i got it.....and accept.......
and i will not take the same mistake.
thx....

PMNOX~~

your source code have a problem.
look original question carefully..

Sample input 's first line
4 4

it respresent 4*4 grid ...but col1 col4 row1 row4 is wall. not col5 row5.
so you can fix and try again....good luck....



[cpp]
for(int i=0;i<=x+1;i++)
{
A [0].bouncer = true;
A [0 ...

i don't find where run-time error....
who can tell me why..

[cpp]
#include<iostream>
#include<string>
#include<queue>
using namespace std;

queue<int> qu;
string sData="";
int start=0;
int rightx=0;
int tree_length=0;
int *position;

void input_data();
void run(string s1);
void cut(string s1);
int ...

it always respound "Wrong Answer"....but i really don't find bug...
anyone can tell me why...
