Decades have passed since the beginning of AtCoder Beginner Contest.
The contests are labeled as ABC001, ABC002, … from the first round, but after the 999-th round ABC999, a problem occurred: how the future rounds should be labeled?
In the end, the labels for the rounds from the 1000-th to the 1998-th are decided: ABD001, ABD002, …, ABD999.
You are given an integer N between 1 and 1998 (inclusive). Print the first three characters of the label of the N-th round of AtCoder Beginner Contest.
比赛从第一轮开始被标记为ABC001，ABC002，但是在第999轮ABC999之后，出现了一个问题：未来的比赛应该如何标记？最后，决定从第1000个到第1998个回合的标签：ABD001，ABD002，...，ABD999。问第n场比赛的前三个字母是什么?
这是一道简单的模拟题,由于题目问的是第n场比赛的前三个字母是什么,并且答案只有ABC和ABD两种,那么我们只需要关心第n场是在1到999之间还是1000到1998之间即可,输出对应答案;
