Write a program that first receives the number $n$ from the input, then takes $n$ other numbers like
$a_1, a_2, \dots, a_n \,$
from the input, and prints the largest one among them.
# Input
The number $n$ is given to you on the first line, then on the next line, $n$ numbers separated by spaces are given to you.
$$ 1 \leq n \leq 10$$
$$1 \leq a_i \leq 1000$$
# Output
Print the largest number on a single line.
# Examples
## Sample Input 1
```
4
1 5 6 2
```
## Sample Output 1
```
6
```
$$\max\{1, 5, 6, 2\} = 6$$
## Sample Input 2
```
3
10 30 20
```
## Sample Output 2
```
30
```
$$\max\{10, 30, 20\} = 30$$
