hi taha,thank you very much for your reply,i changed my code ,but still get WA,i'm so confused.This is my code, could you help me to check it,thank you!!!!

#include <iostream>
using namespace std;
#include <cstring>
#include <cmath>

char str[1001];
int roll,side;

int length(int t)
{
int l;
l=0 ...

Hi sohel,i just obey your way to solve this problem,but always get WA.
Could you give me some samples or this problem have any tricks in it??
thanks

i think this problem is very easy.i just use dfs to solve it. but i always got WA. i don't know why. could somebody give me some I/O please or tell me what's wrong with my code . Thank you very much :D

#include <iostream>
using namespace std;
#include <cstring>

typedef struct
{
char cc;
int ...

hi ,i think this problem could easily to be solved by backtracking.

hi wook,thank you very much!
now i get AC

Could someone tell me how to change the latitude and longitude in this problem?

i don't why i always get WA,could someone give some inputs and outputs?
thank!

#include <iostream>
using namespace std;
#include <cstring>

int stamp[100];
int numOfType;
int customer;
int numOfStamp[100];
int stampUsed[100];
bool tie;
int stamp_list[5];
int now_stamp_list[5];
int now_type_sum ...

hi,jagadish.thank you very much.i finally get AC.
it is the problem of precision.
i run the program well in VC,but wrong in gcc.

hi , jagadish. my program output the same answer pasted above, which one is wrong ??

hi ,i am so confused.can someone tell why i always got WA??

#include <iostream>
using namespace std;
#include <cstring>
#include <cstdio>
#include <cmath>
//#include <fstream>
//ifstream fin("in.txt");
//#define cin fin


int shop[501];
int min;
int money;
int numOfCoin[7];
int num;

void init ...

shamim is correct. Abednego's method gives an answer of -7, not 7.

oulongbin, both players play to get the maximum difference, so if A takes 7, B will take 4 and -10, leaving A with -20 so that B wins with -6 vs. -13. B wouldn't let A pick between -10 and -20 when B could have taken the -10 ...

sorry,i don't very agree with you.
if you are right,i can do this:
A takes 7;
B takes 4;
A takes -10;
B takes -20;
then A is -3 and B is -16;
the answer is 13 greater than 7.

i don't know why the correct is 7.

always get RTE,i do not know why.

#include <iostream>
using namespace std;
#include <cstring>


char arr[50][100];
bool f[50][100];
int len,tlen;
int k;

void indraw(int i,int j)
{
if(i-1>=0 && f[i-1][j] && arr[i-1][j]!='X')
{
f[i-1][j]=false;
indraw(i-1,j);
}

if(i+1<k && f[i+1][j] && arr[i ...

i always get RE,if i enlarge the cycle[][],i get TLE,could someone tell me what's wrong with my code ?thanks.

#include "stdafx.h"
#include <iostream>
using namespace std;
#include <cstring>


int main()
{
char cycle[205][205];
int ci;
int sq[205];
int n;
int sum;
int ts;
char f[205 ...

thanx,i have solved this problem ,backtracking ,thank you!
