Given an integer $X$ between $-10^{18}$ and $10^{18}$ (inclusive), print $\left\lfloor \dfrac{X}{10} \right\rfloor$.

For a real number $x$, $\left\lfloor x \right\rfloor$ denotes "the maximum integer not exceeding $x$". For example, we have $\left\lfloor 4.7 \right\rfloor = 4, \left\lfloor -2.4 \right\rfloor = -3$, and $\left\lfloor 5 \right\rfloor = 5$. (For more details, please refer to the description in the Sample Input and Output.)

- $-10^{18} \leq X \leq 10^{18}$
- All values in input are integers.

Input is given from Standard Input in the following format:

$X$

Print $\left\lfloor \frac{X}{10} \right\rfloor$. Note that it should be output as an integer.

47

4

The integers that do not exceed $\frac{47}{10} = 4.7$ are all the negative integers, $0, 1, 2, 3$, and $4$. The maximum integer among them is $4$, so we have $\left\lfloor \frac{47}{10} \right\rfloor = 4$.

-24

-3

Since the maximum integer not exceeding $\frac{-24}{10} = -2.4$ is $-3$, we have $\left\lfloor \frac{-24}{10} \right\rfloor = -3$.

Note that $-2$ does not satisfy the condition, as $-2$ exceeds $-2.4$.

50

5

The maximum integer that does not exceed $\frac{50}{10} = 5$ is $5$ itself. Thus, we have $\left\lfloor \frac{50}{10} \right\rfloor = 5$.

-30

-3

Just like the previous example, $\left\lfloor \frac{-30}{10} \right\rfloor = -3$.
