### Problem Statement

AtCoder Grand Contest (AGC), a regularly held contest with a world authority, has been held $54$ times.

Just like the $230$-th ABC ― the one you are in now ― is called ABC230, the $N$-th AGC is initially named with a zero-padded $3$-digit number $N$. (The $1$-st AGC is AGC001, the $2$-nd AGC is AGC002, ...)

However, the latest $54$-th AGC is called AGC055, where the number is one greater than $54$. Because AGC042 is canceled and missing due to the social situation, the $42$-th and subsequent contests are assigned numbers that are one greater than the numbers of contests held. (See also the explanations at Sample Inputs and Outputs.)

Here is the problem: given an integer $N$, print the name of the $N$-th AGC in the format AGCXXX, where XXX is the zero-padded $3$-digit number.

### Constraints

• $1 \leq N \leq 54$
• $N$ is an integer.

### Input

Input is given from Standard Input in the following format:

$N$


### Output

Print the name of the $N$-th AGC in the specified format.

### Sample Input 1

42


### Sample Output 1

AGC043


As explained in Problem Statement, the $42$-th and subsequent AGCs are assigned numbers that are one greater than the numbers of contests.
Thus, the $42$-th AGC is named AGC043.

### Sample Input 2

19


### Sample Output 2

AGC019


The $41$-th and preceding AGCs are assigned numbers that are equal to the numbers of contests.
Thus, the answer is AGC019.

### Sample Input 3

1


### Sample Output 3

AGC001


As mentioned in Problem Statement, the $1$-st AGC is named AGC001.
Be sure to pad the number with zeros into a $3$-digit number.

### Sample Input 4

50


### Sample Output 4

AGC051
