9665: ABC183 —— A - ReLU
[Creator : ]
Description
The function ReLU is defined as follows:
$ReLU(x) =
\begin{cases}
x & (x \geqq 0) \\
0 & (x < 0) \
\end{cases}$
Given an integer $x$, find $ReLU(x)$.
$ReLU(x) =
\begin{cases}
x & (x \geqq 0) \\
0 & (x < 0) \
\end{cases}$
Given an integer $x$, find $ReLU(x)$.
Input
Input is given from Standard Input in the following format:
```
$x$
```
```
$x$
