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 functions 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()
```

# Restrictions

`1 ≤ x ≤ 1 000 000 000`

- The problem can only be solved using C++ and you must
`#include "compare.h"`

# Example

```
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`

.
