When King is a second person and has an odd number of people, the size of the first pile needs to be reduced by 1.Because if King is on an odd stone, then the pair of stones in front of King K1,k2.When the other person moves the K1 to top, I can move the K2 to a position in front of the top.So for K2 Stone, if the other side touches it, then I will definitely

LeetCode127-Word ladder Given two words (beginword and endword), and a dictionary's word list, find the length of shortest transformation sequence from beginword to endword, such that: Only one letter can be changed at a timeEach intermediate word must exist in the word listFor example, Given:Beginword = "hit"Endword = "cog"Wordlist = ["hot", "dot", "dog", "lot", "log"]As one shortest transformation is "hit"-> "hot"-> "dot"-> "dog"-> "cog ",Ret

Question: Https://oj.leetcode.com/problems/word-ladder/ Analysis: 1. Find the shortest path and use the BFS algorithm. [3] 2. Find the adjacent relationship between words, and do not use the adjacent matrix. Otherwise, the time limit exceeded will occur. [2] Because not all words need to be adjacent to each other, you only need to solve the neighbors of some words used. It takes a lot of time to obtain the adjacent matrix. 3. After a word is accessed,

Title Link: BZOJ-1115Problem analysisFirst look at the ladder game:Ladder game refers to: the initial n heap of stones, each time can be from any heap to take a number of gravel into the i-1 heap. The person who ultimately cannot operate fails.Solution: The odd bit of gravel heap to do the most basic NIM on it.Why: The winner of the odd digit NIM is always able to win, because if you take a stone from an odd digit to an even digit, it is equivalent to

　　Prior to the BC has done a similar ladder game topic, the problem is moving to the root, the problem is moving to the leaves. In the same order, as long as the final state of the different parity of those positions to do NIM can. So the question gives a condition: the parity of all leaf depths is the same. It is also important to note that the last BC, the root node is not movable, so the root node is an end state node, and here the leaves can also
