47. Innovation workshop (algorithm ):Returns the longest descending subsequence of an array, for example, {9, 4, 3, 2, 5, 3, 2,4,3, 2}
Idea: Dynamic Planning
Calculates the longest descending subsequence of the sequence of the current number. Each time you look for the longest child sequence, scan the child sequence obtained before it, and the first number is sm
Chapter 5 data-centric-Data Access (3), Chapter 5 Access5.1.3 free operation-serialization and deserialization
In Android development, apart from common text and XML files, data is often transmitted or accessed through serialization and deserialization.
Android serialization objects can be implemented in two ways: Serializable interface or Parcelable interface. T

Given an array of s, try to find 3 numbers A, B, C, making a+b+c=0. That is to find out all the 0 and 3 numbers from the collection. For example: Set s={-1,0, 1, 2,-1, 4}, the 3-digit number that satisfies the condition has 2 pairs:(-1,
// Question: decompose a positive integer into a prime factor. For example, enter 90 and print 90 = 2*3*3*5.// Program analysis: to decompose the prime factor of N, you should first find a minimum prime number k, and then follow the steps below to complete:// (1) if the prime number is equal to N, it indicates that the process of decomposing the prime factor is o

Newton's Iterative method was used to find the root of the equation near 1.5:2x^3-4x^2+3x-6=0.Solution: Newton's Iterative method is also called Newton tangent method. Setf =2x^3-4x^2+3x-6,F1 is the derivative of the equation, thef1 = 6x^2-8x+3, and f1= (f (x0) -0)/(X0-X1),

This is a water problem, but I still put it up, because I think I wrote the code is very beautiful (can I have a face?) )The problem description is known as January 1, 2007 for Monday. Design a function to print a calendar after 2007 (including) a month of a year, before 2007, to reject printing. To complete this function, it is also necessary to design the necessary auxiliary functions. Sample input An input example that satisfies the requirements of the topic.Cases:2050
