Test instructions Give three dice, the dice have a k1,k2,k3 face. Each time you roll the dice, you get the number of points and steps to move forward, if the result of the dice is c1,c2,c3 (ordered) back to the original point. Start at 0 and reach the point greater than N, then the game is over. The expectation of the number of dice to be thrown. The transfer equation is: Dp[i] = dp[i+l1+l2+l3]* (1/K1/K2/K3

that the construction [1,7] segment tree is more space-saving and faster to search than the segment tree that constructs [1,10], but the results of the solution are consistent.One thing to be aware of when discretization is that you must first remove the same endpoint before sorting, which reduces the number of elements involved in sorting and saves time.1#include 2#include 3#include 4#include string.h>5 using namespacestd;6 #defineN 101007 #defineM 100000008 BOOLvis[2*n];//Mark appeared poster

Where adjustments of 1 and 3 are performed on a single rotation, 2 and 4 require a double rotation.1. When an insert is made to the left subtree of A's left son, an imbalance occurs:The rotation code is:Static Position singlerotatewithleft (Position K2) { Position

The main idea: a set of n number, now requires that he be divided into a subset of m+1, the subset I set SI represents the sum of the maximum number and the minimum number of squares of the set. The minimum value of all Si's and is obtained. nAnalysis: The M-sets of the optimal solution will certainly not intersect, there will be no empty set, and the number of each subset must be contiguous. Therefore, the number of n can be sorted first, in order to do DP solution. F[I][J] represents the optim

Test instructions: Given some relationships with ax Solution: For each relationship in fact can be built a x->y edge, edge right for B/A, said X Because if you really save b/a, you may lose a lot of precision, but it seems like this can be too. To be more insured, we can take a logarithm, log (b/a) = log (b)-log (a), then multiplication becomes additive, better calculated, and more accurate.The last is to judge, set the final query is k1,k2 two points

One, Configparser module Configparser is used to process files in a particular format, essentially using open to manipulate files. The following format:Create the file name Configparser_f.txt[Section1] #节点K1 = V1K2:v2[Section2] #节点K1 = V1#1. Gets all node Importconfigparserconfig=configparser. Configparser () #创建对象config.
