Given an integer $X$ between $-10^{18}$ and $10^{18}$, inclusive, print $\left\lceil \dfrac{X}{10} \right\rceil$.  
Here, $\left\lceil a \right\rceil$ denotes the smallest integer not less than $a$.

The input is given from Standard Input in the following format:

```
$X$
```

Print $\left\lceil \dfrac{X}{10} \right\rceil$ as an integer.

-   $-10^{18} \leq X \leq 10^{18}$
-   $X$ is an integer.

3

The integers not less than $\frac{27}{10}=2.7$ are 3,4,5,…3,4,5,…. Among these, the smallest is 3, so $⌈\frac{27}{10}⌉=3$.

-1

The integers not less than $\frac{−13}{10}=−1.3$ are all positive integers, 0, and -1. Among these, the smallest is -1, so $⌈\frac{−13}{10}⌉=−1$.

4

The smallest integer not less than $\frac{40}{10}=4$ is 4 itself.
