## Problem :

The included code stub will read an integer, * n*, from STDIN.

Without using any string methods, try to print the following:

`123...n`

Note that “

” represents the consecutive values in between.*...*

**Example** :

`n = 5`

Print the string * 12345*.

**Input Format** :

The first line contains an integer * n*.

**Constraints** :

`1 <= n <= 150`

**Output Format** :

Print the list of integers from * 1* through

*n*

as a string, without spaces.**Sample Input 0** :

`3`

**Sample Output 0** :

`123`

## Solution :

```
if __name__ == '__main__':
n = int(input())
for i in range(n):
print(i + 1 , end = "")
```
