I 've been wrong about my questions recently, orz The question is to find a string with the smallest sum of hamming values, rather than finding the smallest one from the given character. In this case, we will perform column-by-column processing. The character at the current position of the requested string should be the highest number of occurrences in the column followed by the smallest ASCII Value The Code is a little frustrated, and there are too many if statements 1 //#define LOCAL 2 #incl

Today, I used map to rewrite it. Easy to use --! Q: I want to tell you how many sub-trees U V are homogeneous. U belongs to the first tree, and V belongs to the second tree. Use a Map Indicates that the Left and Right trees are merged and mapped to a new tree. Ea

Question:A binary tree with N nodes and a binary tree with M nodes are provided, and information about the left and right Subtrees of each node is provided. The two trees have several identical Subtrees. Ideas:Tree homogeneity, no idea during the competition, other people's problem-solving reports read after the competition. In fact, it is a hash value for the left and right S

Problemid = 4705 Question: Give Two Binary Trees A and B, and ask how many pairs have the same structure as the sub-tree a in a and the sub-tree B in B. Idea: hash. Different numbers correspond to different structures. For example, 1 represents a separate leaf node, 2 indicates that the Left subtree is a leaf node without the right subtree... every time a new subtree occurs, it is recorded, the record method is to use the DFS backtracking p

Label: style blog Io OS AR for SP 2014 on [Description]: the meaning of the question is to enter a string and ask how many different types of characters we have. That is to say, once a character appears, it will not be counted in the next time, especially ff, fi, FL, FFI, FFL. [Analysis]: After briefly explaining the meaning of the question, we can solve the problem. Code: // 196 K 0 Ms # include poj 3602 typographical ligatures

Test instructions: Given a sequence of DNA of length n of M, a shortest sequence of DNA is obtained, which minimizes the total hamming distance.Hamming the distance is equal to the number of different positions of characters.Analysis: See this problem, my first feeling is to calculate the time complexity, good small, nothing, completely can violence, as long as the same position on each string,The choice appears most, if has the same choice ASIIC code small (because requires the dictionary order

Test instructionsTwo trees (10^5 nodes) ask how many of them are isomorphic to each otherIdeas:The isomorphism of a tree is generally judged by a hash.The hash function is 1, val=a 2, val = (val*p) ^soni%q where Soni is the hash value of the sub-tree 3, Val=val*b%qNote that the son value should be sorted (this is because the left and right subtrees are separated so they do not have to be sorted)Code:#include ZOJ 3602 Count the Trees
