Print Function in Python - Hacker Rank Solution

Problem


Tutorial
In Python 2, the default print is a simple IO method that doesn't give many options to play around with.
The following two examples will summarize it.
Example 1:
var, var1, var2 = 1,2,3
print var
print var1, var2

Prints two lines and, in the second line, var1 and var2 are separated by a single space.

Example 2:
for i in xrange(10):
    print i,

Prints each element separated by space on a single line. Removing the comma at the end will print each element on a new line.
Let's import the advanced print_function from the __future__ module.
Its method signature is below: 
print(*values, sep=' ', end='\n', file=sys.stdout)
print(value1, value2, value3, sep=' ', end='\n', file=sys.stdout)

Here, values is an array and *values means array is unpacked, you can add values separated by a comma too. The arguments sep, end, and file are optional, but they can prove helpful in formatting output without taking help from a string module.
The argument definitions are below:

sep defines the delimiter between the values.
end defines what to print after the values.
file defines the output stream.

in Python 2 print_function is much faster than the default print
Read an integer N.
Without using any string methods, try to print the following:
123...N
Note that "..." represents the values in between.


Input Format :

The first line contains an integer N.

Output Format :

Output the answer as explained in the task.


Sample Input :

3

Sample Output :

123
