Some small algorithms are of the Java version, and a large number of questions on the network are aimed at C ++. Therefore, Java implementation is rare, but they are the basis of the test,
The implementation is the same. You can broaden your thinking and be helpful.

What is the result of a certain convincing pen question in a certain year? The answer is 4. Why?
My understanding (do not know if it is correct ):
A is an array pointer of the int type [5
Exercise 3-1 Score StatisticsEnter some student's score, which score appears the most times? If there are multiple parallel, from small to large output.Task 1: Non-negative integers with fractions not exceeding 100Task 2: The score does not exceed 100 of the nonnegative real number, but retains a maximum of two decimal
1. Simple arithmeticAlgorithm: For example, 1X2 + 3/3x4 + 8
The arithmetic above is relatively simple, with no parentheses. It is just a general operation. Now the only thing we need to do is to figure out the priority. In addition to the data structure, we can implement the stack assistant.
The basic algorithm is as follows: there must be two stacks, one for data storage, and the other for operators. I
