#2375. 疯狂的涂色
题目描述
小t非常喜爱画画，但是他还是一个初学者。他最近费尽千辛万苦才拜到已仙逝的达芬奇为师（神仙？妖怪？谢谢）。达芬奇果然是画鸡蛋长大的，让小t一入门就拿着一张白纸条疯狂地涂色。假设纸条被划分成了n个区域，用1~n的整数从左到右顺序编号，达芬奇总共下达了m条指令。第I条指令是让小t把编号为(Ip+q)mod n+1与(Iq+p)mod n+1(p,q为常整数)之间的区域（连续的一段区域）涂成第I种颜色。你可以假设达芬奇家中颜料的颜色数足够多（达芬奇是画鸡蛋长大的）。
现在由于达芬奇下达的指令过多，小t一时应付不过来。达芬奇只让他回答每一个区域最后的颜色。趁达芬奇还在"五谷轮回之所"忙碌时，小t偷偷的请让你这个计算机高手帮他算出最后的颜色状态，并告诉他。时间紧迫，要快哟！（达芬奇的指令次数多到恶心）
输入格式
为四个整数n,m,p,q。
输出格式
n行，第I行代表最后第I个格子的颜色。白色编号为0。
