He is too selfish, so for a given n he wants to obtain a string of n characters, each of which is either ‘a’, ‘b’ or ‘c’, with no palindromes of length 3 appearing in the string as a substring. For example, the strings “abc” and “abca” suit him, while the string ...

Given a linked list, determine if it has a cycle in it. Follow up: Can you solve it without using extra space? 题意:如何判断链表是否有环 这是一个经典的问题,后面还有追问: 如果有环,计算环的长度? 找到碰撞点的位置? 首先,如何找环,设计两个指针,分别从链表的头节点开始,...猜...
while I was allowing proper nouns to appear anywhere, not just in the final "Panama": NP => ProperNoun NP => IndefArt Noun IndefArt => "a" | "an" Guy Steele suggested I should also try allowing other noun phrases, such as "two Xs". Gold said the language induction problem ca...

python3 Determine whether an integer is a palindrome. Do this without extra space. Some hints: Could negative integers be palindromes? (ie, -1) If you are thinking of converting the integer to string, note the restriction of using extra space. You could also try reversing an integer. Howe...
