Fools and Roads 经典的lca前缀和问题

题意：给你一棵树，有n个点，并按顺序给你n-1条边，然后有m次操作，每一次操作输入两个点a，b表示从a走到b点，把路径中的所有边都染色一遍，最后按顺序输出所有边被染色的次数。第一眼看这道题就感觉这是一个很经典的问题。首先我们知道对于a，b必然先找出ab的lca。然后朴素想法：从a向上到lca，从b向上到lca，每条边的flag都++，最后输出，这种做法肯定是TLE的，n=10W的数据量不会给你这么

ALL ROADS LEAD TO ROME

2013年跟着旅游团游意大利，创下了4天游6城的记录。晚上从斯图加特乘大巴车，一路往南，穿过阿尔卑斯山脉，途经瑞士，一路狂奔至威尼斯，早上到达威尼斯的时候太阳刚刚升起，阳光灿烂。下午从威尼斯一路再往南，至弗洛伦撒，比萨，基本上是上车睡觉，下车拍照。中国导游的三寸不烂之舌倒是让一路欢声笑语，再往南就是罗马。回城由罗马一路狂奔向北到米兰。下午再经瑞士，一路美妙的湖光山色，令我惊呼连连，被人笑做没见过世
