what is test case 7?
I think my doing well.
#include<stdio.h>
int main()
{
    int n,val[1001],pos1=2,pos2=1,sum[1001];
    scanf("%d",&n);
    for(int i=1;i<=n;i++)
        scanf("%d",&val[i]);
    for(int i=2;i<=n-1;i++)
    {
        sum[i]=val[i-1]+val[i]+val[i+1];
    }
    for(int i=2;i<=n-1;i++)
    {
        if(sum[i]>=sum[i+1])
        {
            sum[i+1]=sum[i];
            pos2++;
        }
        else if(sum[i]<sum[i+1])
        {
            pos1+=pos2;
            pos2=1;
        }
    }
    printf("%d %d",sum[n-1],pos1);
}

I don't understand where I'm wrong. I tried the sample and the result is right!
#include<iostream>
#include<map>
using namespace std;
int main()
{
    int n,num;
    map<char,int> val;
    val['a']=1;val['b']=2;val['c']=3;val['d']=3;val['e']=3;val['f']=3;val['g']=2;val['h']=1;
    val['1']=1;val['2']=2;val['3']=3;val['4']=3;val['5']=3;val['6']=3;val['7']=2;val['8']=1;
    char xy[1];
    cin>>n;
    while(n--)
    {
        cin>>xy;
        num=val[xy[0]]+val[xy[1]];
        if(num==6)
            num+=2;
        if(num==5)
            num++;
        cout <<num<<endl;
    }
}

import  java.util.*;
public class Penguins1585 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n = Integer.parseInt(in.nextLine());
        int a=0,b=0,c=0;
        for(int i=0; i<n; i++){
            String s = in.nextLine();
            String s1=s.substring(0,1);
            if(s1.equals("E"))a++;
            else if(s1.equals("M"))b++;
            else c++;
        }

        if(a>=b && a>=c)System.out.print("Emperor Penguin");
        else if(b>=a && b>=c) System.out.print("Macaroni Penguin");
        else System.out.print("Little Penguin");



    }

}

The question is simple. So is my code. See below It gets AC in VC++2000.
But why does it get WA#1 in gcc4.7.2 and gcc4.7.2-c++11, until I replace the while-scanf loop with the commented while-cin loop?

Thanks.

#include <iostream>
#include <cstdio>
#include <cstdlib>
#include <cmath>
#include <vector>
int main()
{
    std::vector<long long> v;
    long long t;
    while (std::scanf("%lld", &t) != EOF) {
    // while (std::cin >> t) {
        v.push_back(t);
    }
    for (int i=v.size()-1; i>=0; --i) {
        printf("%.5f\n", sqrt((double)(v[i])));
    }
}

In this test use LONG INT. I use INT and got WA, but later I use LONG INT and got AC.

#include <stdio.h>
#include <math.h>
#define N 4
int main()
{
    long double a[N];
    long double b[N];
    int i = 0;
    while(i < N)
    {
        scanf("%Lf",&a[i]);
        b[i]=sqrt((long double)a[i]);
        i++;
    }
    if(i == N)
    for(i= N - 1; i>=0; i--)
    {
        printf("%.4Lf\n", b[i]);
    }


}


seems to return the right values. But writes "Wrong answer". Thanks!

"...solutions for which the outcome has changed."

Is the outcome change
"WA 6" -> "WA 8"
a real change on which a letter is sent?

Or only outcome code (WA, AC, ...) make sense, not a test number??

Help me find a mistake

using System;
using System.Collections.Generic;

            Array.Sort(a);
            int[] ab = a.Intersect(b).ToArray();
            Console.WriteLine(ab.Length);

        }
    }
}

Please help pass the test 6. It is very necessary.

                    }
                }
            }
            Console.WriteLine(maxsum + " " + j);
        }
    }
}

Can anyone help me ? I have WA16 and i don't know what is wrong with my code .


UPD : Test 16 is a big test . I replaced in one place int with long long and i got AC.
Good Luck :) !

What are the values of input in it?

Can someone give me the test #7. I've got WA in this test.

Thank's.

It seems that my program gives right answers to all tests, but, nevertheless, WA #2 :(((

TL for this problem is 0.5s but list of successful submissions contains times up to 2s.

the turning point should be left to LAST group.
