## Task

There's a hidden number $x$ and you are given the task to find its value using the following function:

```
int compare (int guess) {
return guess > x;
}
```

In other words, the function returns $1$ if your guess is bigger than the number you're trying to find, $0$ otherwise.

You must only implement the `solve`

function with the following header:

```
int solve()
```

## Constraints and clarifications

- $1 \leq x \leq 1 \ 000 \ 000 \ 000$
- The problem can only be solved using C++ and you must
`#include "compare.h"`

.

## Example

```
#include "compare.h"
int solve() {
int x = 2;
if (compare(x))
return 1;
return 1'000'000'000;
}
```

### Explanation

The sample function only gives the right answer if $x$ is $1$ or $1 \ 000 \ 000 \ 000$.
