I don't understand what problem is it


#include <stdio.h>
#include <math.h>

int main()

    long double i[10000] = {0};
    int c,tmp,j=0;
    while ((c = getchar()) != EOF)
    {
        if ( (c != ' ') && ( c != '\n' ) && ( c != '\t' ) && ( c != '\0' ) )
        {
            i[j] = i[j]*10 + ((int)c - 48) ;
        }
        if ( ( tmp!=' ' && tmp!='\n' && tmp!='\t' && tmp!='\0' ) && ( c == '\0' || c==' ' || c=='\n' || c=='\t' ) )
            j++;
        tmp = c;
    }
    for ( j-- ; j>=0 ; j--)
    {
        printf("%Lf\n", sqrtl(i[j]));
    }
    return 0;
}

What is about the test 3 ?

#include <stdio.h>
#include<math.h>
void main()
{
float a[1024];
    int i=0,count=0;

    while(scanf("%f",&a[i]))
    {

        a[i]=sqrt((float)a[i]);

        count++;
        i++;
    }

        for (int i=count-1;i>0|i==0;i--)

            printf("\n%.4lf",a[i]);
}

Can number of decks for already placed ships be more than 4?

In another words, is this test possible:

30000 30000 1
1 1 30000 H
1

?

More a puzzle than a programming challenge....

Give me more examples to test, pls.

I copy source code then it told me compilation error?

Edited by author 07.04.2008 14:47

What's wrong with test 3? My programm passes everything, that has ever been suggested on this forum. Could you give another test for me? Can WA mean that text is bigger than 10000 symbols, as I declare(because I have Compillation error in case of t[100000] for some reason)? Sorry for my bad english.

#include<stdio.h>

int arr[11];
int num = 1;
int prime[10000];
int ans = 1;
int main()
{
    for( int j = 0  ; j< 10 ; j++ )
    {
        scanf("%d",&arr[j]);
        if( arr[j] == 1 )
        {
            continue;
        }
        for( int i = 2 ; i <= arr[j] ; i++ )
        {
            while( arr[j] % i == 0 )
            {
                prime[i]++;
                arr[j] = arr[j] /i;
                if( arr[j] == 1 )
                {
                    break;
                }
            }
        }
    }

    for( int i = 2 ; i < 10001 ; i++ )
    {
        ans *= (prime[i]+1) % 10 ;
    }
    ans = ans % 10;
    printf("%d\n",ans);
    //scanf("%d",&prime[0]);
    return 0;
}

My idea of the problem was the following:
1) I know, how many K-ships can be placed on the FREE board.
It's a rather simple formula
2) After that I check each placed ship. For him I found all the K ships that cannot be placed on the board thanks to this ship and add them to the special array (if they aren't there already). After that I subtract the number of elements in the array out of FREE board amount and that's the answer.
Who can give me test 4?

Test : abcdefgh
Answer : dbacfeg
Is this answer correct?

it gives good output for every test i came up with...
i dont know where is the mistake and code is very simple
help pls



#include <iostream>

using namespace std;

int main(){

    int n,i;
    int* tab;
    int tabL[11]={0};
    cin >> n;
    tab = new int [n];
    for(i=0;i<n;i++){
            cin >> tab[i];
            tabL[tab[i]]++;
            }
    for(i=0;i<11;i++){
             if(tabL[i]!=0){
                    cout << tabL[i] << " " << i << " ";
                    }
             }
    getchar();getchar();
    return 0;

}

пробовал разные способы вычисления, упираюсь в 33 тест.
Какие есть мысли?

I wonder the teat #9...

How i can read all numbers in JAVA?

не могу подобрать тест определяющий ошибку....

#include <stdio.h>
int main(){
int code1;
int code2;
scanf("%d\n%d", &code1, &code2);
if(code1 == 0001 || code2 == 0000 || code1 == code2)
printf("no");
else printf("yes");
}

I did not understand the task and made program for first test. Why i have WA in test 14?
