Почему Runtime error??

Всем привет! Я написал реализацию программы на Java. Проверка выдает Runtime error. Программа принимает n, после чего слушает ввод и после каждого введенного слова выводит ответ. Выглядит это так:

9
0010100011 //мой ввод
001000011  //вывод программы
00010010   //мой ввод
000100101  //вывод программы

Ctrl - C

Скажите, правильно ли реализовал ввод/вывод данных?
Спасибо!

can you find other sequence like this ,
input = output

Please publish here some tests
All test cases invented by me passed but I have got here WA on test 3

Try this test:
3 1
1000 0
1000 6
100 10
2 5

answer is:
1985.0

            if (max < a[i]){

            }
        }
        else{////if digits
            a[i] = s[i] - 48;
            if (max < a[i]){
                max = a[i];
            }
        };

    for (k = max; k <= 36; k++)
    {

        for (int i = strlen(s) - 1; i >= 0; i--)
        {
            res = res + pow(k, i)*a[i];
        }
        if (res % (k - 1) == 0){
            found = 0;
            break;
        }

    if (found==0){
        cout << k;
    }
    else{
        cout << "No solution.";
    }
    system("pause");
}
I think that problem in large numbers in tests, am I right?

See on one iteration of "for":
let be x and y on start:x1 and y1.
then after each change it'll be for x1 x2...x3; for y1 y2...y3;
so you have to find out x3 and y3 through x and y on start(x1 and y1);
Something like that x3=y1.
Good luck and sorry if my English is not enough good for explaining it)

777 313 465 99 1

in the test above, how Daenerys  can win ??? While we can divide:
#Daenerys  777 -> 3 heaps (259)
- 313 -> can't divide
#Stannis  465 -> 3 heaps (155)
#Daenerys 99  -> 3 heaps (33)
#Stannis  33 -> 3 heaps (11)
- 1   -> can't devide
==> Stannis  is the winner

I don't understand how the answer can be 15.

Since the first 2 people got 0 correct predictions and the last person got 1 correct prediction, shouldn't the amount paid only be 5?

dp[i][j] - represents number of staircases with i cubes and with the height of last block j.
Answer is dp[n][1] + dp[n][2] + dp[n][3] ... dp[n][n].

At first check all tests with n<=4. If all of them cheked already then try to check all cells for n=8 (1/1; 1/2; 1/3; 1/4; 2/2; 2/3....)and for n=9. Don't be afraid you'll find your mistake on first tests))

can someone give me some tips or tests?

#include <iostream>
#include <math.h>
#include <iomanip>

using namespace std;

int main()
{
    double a[100000];
    int i, n;
    cin >>n;
    for (i=1; i<=n; ++i)
    {
        cin>>a[i];
    }
    for (i=1; i<=n; ++i)
    {
        a[i] = sqrt(a[i]);
    }
    for (i=n; i>=1; --i)
    {
        cout << fixed << setprecision(4) << (a[i]) << endl;
    }
}

What is the criterion of optimality of the partition ?
