This is a big point I think should take care.

this is my code in C++ but the system does not accept it. please help me.
---------------------------------------------------------------
#include<iostream>
using namespace std;
int main()
{
    long long int nums[100][100];
    char x[90];
    int n, m;
    long long int id, temp;
    cin>>n;
    for(int i=0; i<n; i++)
    {
        cin>>id>>m;
        nums[i][0]=id;
        nums[i][1]=m;
    }
    for(int i=0; i<n; i++)
    {
        for(int j=i+1; j<n; j++)
        {
            if(nums[j][1]>nums[i][1])
            {
                temp=nums[j][0];
                nums[j][0]=nums[i][0];
                nums[i][0]=temp;
                temp=nums[j][1];
                nums[j][1]=nums[i][1];
                nums[i][1]=temp;
            }
        }
    }
    for(int i=0; i<n; i++)
    {
        cout<<nums[i][0]<<" "<<nums[i][1]<<endl;
    }
    return 0;
}

Такой вывод для первого теста подходит, т.к. "говорит" WA2
Console.Write("3 5\n26 4\n22 4\n16 3\n20 3\n1 2\n11 2\n7 1\n");

А этот WA1. В упор... =( .
--------------------------------
using System;
using System.Collections.Generic;

class Program
{
    struct TRec { public int ID, M; }
    static int Comp(TRec x, TRec y)
    {
        if (y.M < x.M) return -1;
        else if (y.M > x.M) return 1;
        else return 0;
    }

    static void Main()
    {
        int N = int.Parse(Console.ReadLine());
        List<TRec> D = new List<TRec>();

        string[] RecStr;
        for (int i = 0; i < N; i++)
        {
            RecStr = Console.ReadLine().Split(' ');

            TRec R = new TRec();
            R.ID = int.Parse(RecStr[0]);
            R.M = int.Parse(RecStr[1]);
            D.Add( R );
        }

        D.Sort(Comp);

        foreach (TRec X in D)
            Console.Write("{0} {1}\n", X.ID, X.M);
        Console.ReadLine();
    }
}
Делаю в C#2012. Неужто в 2010 quick_sort работает по другому?

very strange, when using printf("%lld", ans); -> WA6
however, cout << ans << endl; ->AC

Обратите внимание на результат при N = 1000000000.
А точнее на его размер 555555555888 в 32 бита он не поместится.
8 тест из-за этого выдает "Wrong answer".

Hi i'm getting WA for #10, can anyone help with this?
My code works for everything ive tested so far
public static void main( String [] args){
    int a,b;
    Scanner sc = new Scanner(System.in);
    a = sc.nextInt();
    b = sc.nextInt();
    int[] array = new int[b];
    for( int i = 0; i < b; i++)
        array[i] = sc.nextInt();
    int carry = 0;
    for( int i = 0; i < b; i++){
        array[i] = array[i] + carry;
        if(array[i] > a)
        carry = array[i]%a;
        else carry = 0;
                array[i] = array[i] - carry;
    }
    int answer=0;
    array[b-1]+=carry;
    int current  = 0;
    for( int i = 0; i < b; i++){
        if(array[current] <= a){
        array[current] = 0;
        current++;
        }
        else
        array[current] = array[current] - a;
    }
        for( int i = 0; i < b; i++)
            answer+=array[i];
        System.out.println(answer);

}

subj

At first I was also pissed off but this problem is awesome in that it makes you remember forever that you need to first read input/ouput rather than problem itself!

#include<iostream>
#include<stdio.h>
#include<stack>
#include<cmath>
using namespace std;
int main () {
    stack <unsigned long long int> a;
    unsigned long long int num;
    while (scanf("%llu",&num)!=EOF) {
        a.push(num);
        }
    for (;;) {
        printf("%.4lf\n",double(sqrt(double(a.top()))));
        a.pop();
        if (a.empty()==1) break;
        }
    return 0;
}

That's my code. I have WA1. But my program writes right answer for the sample test. Where is my mistake is it printf (i tried with cout but the result was the same.)?

I have a problem with 5 test case. Firs I had Runtime Error, when I add lines:

   if(nextWord == null)
      continue;

Runtime Error changed to WA.

I'm using Java and i read my input as follow:
    StreamTokenizer in = in = new StreamTokenizer(new BufferedReader(new InputStreamReader(System.in)));

    private static int nextInt() throws IOException {
        in.nextToken();
        return (int) in.nval;
    }

    private static String nextString() throws IOException {
        in.nextToken();
        return in.sval;
    }

Somebody had a wrong answer in test 6? I can't understand what exactly can be wrong :(
Please, help

Please explane what is K.
What it means K=10?

To those who WA 8:
Try to change your epsilon to something else then 1e-14.
I changed that to 1e-8 and then I got AC.

Also, don't calculate S△ABC as 0.5*AB*AC! It should be 0.5*AB*AC*sin∠A

Name of a compartment might consists digits.

wrong answer test 13
why

Don't it mean he only deliver one whisky on one day?
I don't know the test while the others programmer offer...
Who can tell me what the problem mean?

using System;



namespace ConsoleApplication4
{
    class Program
    {
        static void Main()
        {  int x = 1;
            do
                        {
                Console.WriteLine("введите число");
                String строка = Console.ReadLine();
                Single X;
                X = Single.Parse(строка);
                {
                    if (X <= 4 && X >= 1 )
                    {   Console.WriteLine(" few");}
                         if( X <= 9 && X >= 5)
                         {   Console.WriteLine("several");
                    }
                    if (X <= 19 && X >= 10 )
                    {Console.WriteLine("pack");}
                          if( X <= 49 && X >= 20)
                          {  Console.WriteLine("lots");}
                          if (X <= 249 && X >= 100)
                          { Console.WriteLine("throng"); }
                          if (X <= 99 && X >= 50)
                          { Console.WriteLine("horde"); }
                          if (X <= 499 && X >= 250)
                          { Console.WriteLine("swarm"); }
                          if (X <= 999 && X >= 500)
                          { Console.WriteLine("zounds"); }
                          if (  X <= int.MaxValue   && X >= 1000 )
                          { Console.WriteLine("legion"); }
                    }
                }
            while (x != 0);
        }
    }
}

This topic is devoted to trolled ppl :D


God damn it I was ashamed after typing so many string super duper cumbersome functions XD
