This contest, AtCoder Beginner Contest, is abbreviated as ABC.
When we refer to a specific round of ABC, a three-digit number is appended after ABC. For example, ABC680 is the 680th round of ABC.
What is the abbreviation for the N-th round of ABC? Write a program to output the answer.

-----Constraints-----
 - 100 ≤ N ≤ 999

-----Input-----
Input is given from Standard Input in the following format:
N

-----Output-----
Print the abbreviation for the N-th round of ABC.

-----Sample Input-----
100

-----Sample Output-----
ABC100

The 100th round of ABC is ABC100.
