Question: Ultraviolet A-111 history grading (LIS) Find the longest Lis. However, the question is really wrong. For example, 3 1 2 4 9 5 10 6 8 7 indicates that the first historical event is ranked third, and the second historical event is ranked 1st, first, sort the event in chronological order. New Order: 2 3 1 4 6 8 10 9 5 7. Solution: Lis. Code: #include Uvs-111 history grading (LIS)

Recommendation 111: Avoid bidirectional couplingBidirectional coupling refers to the mutual reference between two types. The following code is a typical bidirectional coupling: class A { private b b; Public void MethodA () { b.methodb (); } } class B { private a A; Public void MethodB () { A.methoda (); } }Two-way coupling under the same project, the

UVA 111 History GradingMany problems in computer science involve maximizing some measure according to constraints.Consider a history exam in which students is asked to put several historical events into chronological order. Students who order all the events correctly would receive full credits, but how should partial credits is awarded to Students Who incorrectly rank one or more of the historical events?Some possibilities for partial credits include:

Original title: 111. Minimum Depth of Binary Tree Read the question: To find the minimum depth, which is similar to the maximum depth of the tree, it is only necessary to note that when the Zuozi or right subtree is empty, the minimum depth is not 0, but depends on the minimum depth of the nonempty tree. # Definition for a binary tree node. # class TreeNode (object): # def __init__ (self, x): # self.val = x # self.left = None
