Given A binary search tree (BST), find the lowest common ancestor (LCA) of the Given nodes in the BST.According to the definition of the LCA in Wikipedia: "The lowest common ancestor is defined between," nodes V and W as the L Owest node in T, have both V and W as descendants (where we allow a node to be a descendant of itself).

Function call in C Language 03-maximum common divisor and minimum common multiple // Function call/* ========================================== =============================== question: calculate the maximum common divisor and the least common multiple of two numbers. For example, the maximum

This article mainly introduces the common algorithms used to calculate the maximum common approx of two integers in php. The example summarizes the three common methods for finding the maximum common approx. It has some reference value. For more information, see This article mainly introduces the

I need to write an algorithm in my work recently, and I have found a very interesting thing when I finish writing this algorithm. The algorithm needed is this: for A, b two string, find up to K common substrings, making this K substring length and maximum. At first, I thought about some messy ideas.Error 1: For example, each time you find the longest common substring, find a substring, delete the substring

Topicthe longest common child stringGives two strings, finds the longest common substring, and returns its length.Sample ExampleGive a="ABCD", b="CBCE", return 2NoteThe characters of the substring should appear consecutively in the original string, which differs from the subsequence.SolvingAttention:Subsequence: This sequence is not contiguous in the original string, but is spaced, such as: ABCDE and ambmcm

Problem Description:Substring should be better understood, as to what is a subsequence, here is an example: there are two strings: Cnblogs belong such as sequence Bo, BG, LG in the parent string cnblogs and belong have appeared and the order of occurrence and the parent string consistent, we call it a common sub-sequence. The longest common subsequence (longest Common
