(1) Description: enter an integer array to determine whether the array is a result of post-sequential traversal of a binary search tree. If Yes, Yes is output; otherwise, No is output. Assume that any two numbers in the input array are different.

Returns the number of digits of a certain factorial. The most popular method on the Internet is to calculate the logarithm and calculate it hard. The cards are sometimes used, and there are still some clever components. The positive solution may be

In the process of debugging the HAC-UM96, encountered a lot of problems, and may not use 51 for a long time, write the program has no idea, but later I found the write feeling. My biggest difficulty lies in the hardware. I have never felt about the

The InstallShield script language is similar to the C language. You can use the InstallShield wizard or template to generate a BASIC script framework. You can modify and add the script as needed. I. basic syntax rule 1. the Boolean value of the

# Ifdef _ cplusplus, which is generally used to Output C ++ code in the form of standard C (called in the form of C ), this is because C ++ is often considered as a superset of C, but the C ++ compiler is still different from the C compiler. It is

The question is not difficult, but the input and output data is large and the format is large. You need to think about it and pay attention to it. It took a lot of time, but it was a bit rewarding. First, the string type can only use cin, but not

A Matrix maze is known as a Matrix maze. It is filled with electricity at the beginning, and requires that the given point be traversed. Each movement consumes 1, several batteries in the Maze can be fully charged (each battery can only be used once)

It mainly includes creating, inserting, deleting, locating, and merging linked lists in the linked list operation. [Cpp] // LinkList. cpp: Defines the entry point for the console application. // # include "stdafx. h "# include" iostream "# include"

In STL, the basic containers include: string, vector, list, deque, set, map set, and map are unordered storage elements, you can only access the set: set through the interface provided by the set: set to determine whether an element is in a group.

An 8x8 lattice subgraph, each of which has no more than 2000001 stones, goes from () to (). The passing lattice can no longer go and can only go up, down, right, in the upper right, lower right, and five directions, I asked if I could just collect M

Foreword alas, I always feel that I can only do my best to help my teachers. In the past year, students are still reliable, and their educational qualifications are highly reliable, so they cannot reflect all problems, but it can reflect most of the

Requirement: scan the str string from left to right, move all the characters on the left of lowercase letter o to the right of the string, and delete the lowercase letter o, scan the str string and perform the preceding operations until all

This type of question generally has two forms. The common point is that the central sequence is known. If there is no central sequence, a tree cannot be uniquely identified. we know the Pre-and mid-order sequences of Binary Trees to solve the tree.

It took a long time. The difference constraint is finally written. If the food cannot afford to hurt ~~~ Difference constraints: 1. Find the constraints. 2. Create a graph. 3. Use spfa to find constraints. You need to understand the meaning of the
