I also try many time in this question, but all WA.
I know that it is a precision problem after read these post.

Can anyone help me improve the precision?

#include <iostream>
#include <stdio.h>
#include <algorithm>
#include <cmath>
using namespace std;

struct Complex{
double x,y;
bool operator ...

I have re-submitted the program. I find it is WA now.
Do another people also face this problem?

Thank you for Jan.

It is a logic error rather than precision error.

I post my code here.
I will delete before the day after tomorrow.

Hope someone can help me debug it.

Remove because Acc

For this problem I didn't care for any precision error at all.
Check your code again, may be you are doing some other mistakes.

Thank you for you advice.

I have checked for the sample case posted here.
However,I find no bug to my program.

I am suffer from precision error in this problem.
Can anyone help me?

Can paste some testcase here?
I get WA in this problem with reason unknow.

Anyone can help me?

You may try this sample input.

thank you.

I change the code, just do the absolute value by coding.

I dont know why I get PE.
Anyone have an idea?

Here is my code.

#include <iostream>
#include <algorithm>
#include <string>
#include <vector>
#include <queue>
#include <map>
using namespace std;

int main(){
int n; cin >> n; cout << "SHIPPING ROUTES OUTPUT" << endl;
for(int i=1;i<=n;++i){
cout ...

I dont know why it is WA. Can anyone help me?
Here is my code.

#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main(){
int c=1; double y,z; char x; vector<vector<double> > v;
while(cin >> x,x!='*'){
vector<double> w;
for(int i=0;i<4;cin>>y,w.push_back(y),++i ...

I dont know why i get compile error.
Can anyone tell me what is wrong?

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

int main(){
long long x,y;
while(cin >> x >> y) cout << abs(x-y) << endl;
}

I dont know why I get WA.
If you find any error in the output, please give me the sample input.

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

int main(){
int p; cin >> p;
for(int i=0;i<p;++i){
if(i>0) cout << endl;
int a=0,b=0,c=9999,d=9999,w,x,y,z;
for(int j=0;j<2;++j){
bool m ...

thank you
