思路分析:思路应该比较简单也很容易想的来,就是比较两个节点的最近的祖先节点,要对每个节点依次记录下他的所有祖先节点,包括其自己,因为自己也算自己的祖先节点,这一点题目中没有明确指出 所以比较坑. 我们可以用一个数组表示某个节点的父节点是谁,在判断的时候顺着数组遍历下去就能达到根节点1,并依次记录下该节点的所有的祖先节点.再与另外一个节点的所有的祖先进行比较. Problem C. 最近公共祖先 题目描述 给出一棵有N个节点的有根树TREE(根的编号为1),对于每组查询,请输出树上节点u和v的…

题目一:输入一个英文句子,翻转句子中单词的顺序,但单词内字符的顺序不变.为简单起见,标垫符号和普通字母一样处理.例如输入字符串“I am a student.”,则输出“student. a am I ”. 解题思路:第一翻转句子中所有的字符.比如翻转“I am a student.”中所有的字符得到“.tneduts a ma I”,此时不但翻转了句子中单词的顺序,连单词内的字符顺序也被翻转了,第二步再翻转每个单词中字符的顺序,就得到了“student. a am I”.这正是符合题目要求的输…
