Question

谁能翻译一下这段题目

The Children’s Day has passed for some days .Has you remembered something happened at your childhood? I remembered I often played a game called hide handkerchief with my friends.
Now I introduce the game to you. Suppose there are N people played the game ,who sit on the ground forming a circle ,everyone owns a box behind them .Also there is a beautiful handkerchief hid in a box which is one of the boxes .
Then Haha(a friend of mine) is called to find the handkerchief. But he has a strange habit. Each time he will search the next box which is separated by M-1 boxes from the current box. For example, there are three boxes named A,B,C, and now Haha is at place of A. now he decide the M if equal to 2, so he will search A first, then he will search the C box, for C is separated by 2-1 = 1 box B from the current box A . Then he will search the box B ,then he will search the box A.
So after three times he establishes that he can find the beautiful handkerchief. Now I will give you N and M, can you tell me that Haha is able to find the handkerchief or not. If he can, you should tell me "YES", else tell me "POOR Haha".

儿童节已过去了几天。你是否还记得你小时候的往事？我记得我经常与朋友玩一个叫“藏手绢”的游戏。现在我给你介绍下这个游戏。假设有N人玩这个游戏，他们围坐在地上成一个圆圈，每人背后有一个盒子。当然其中一个盒子里有一条美丽的手帕。
然后Haha（一个我的朋友）被叫去找手帕。但他要个怪癖，每一次都会搜找与他所站在盒子间隔M-1个盒子的盒子。比如这里有A、B、C 三个盒子，Haha站在A盒子处。如果现在他决定M值为2，那他会先去搜A盒子，然后再搜C盒子，因为2-1=1 盒子，A盒子与C盒子之间隔了一个B盒子。然后他会搜B盒子，再然后是A盒子。
所以三个回合后他可以找到美丽的手帕。现在我给你N值（人数）与M值，你们能告诉我Haha能否找到手帕。如果他能找到，你回答“Yes”，否则你回答“可怜的Haha”。

（怕你没看懂，这里是解释：因为M=2，M-1=1，所以每次选择间隔1个盒子，顺序是按A-B-C-A-B-C不断循环，第一是A盒子，跳过1个盒子后是C，再跳1个盒子后是B，再跳1个盒子后是A，不断循环；如果M=3，那就是每次跳过2个盒子，也就每次都是A盒子）
