# Category: Mathematics

Applied Mathematics is a general term for mathematical theories and methods with a clear application purpose. The study of how to apply mathematical knowledge to the branches of mathematics in other categories (especially science) can be said to be the opposite of pure mathematics. Including differential equations, vector analysis, matrix, Fourier transform, complex analysis, numerical methods, probability theory, mathematical statistics, operations research, control theory, combinatorial mathematics, information theory and many other branches of mathematics, as well as from various application fields The study of the mathematical problem presented. Computational mathematics can sometimes be regarded as part of applied mathematics.

## Non-boring sequences(分治)

We were afraid of making this question too boring, so we decided to make this question super short. A sequence is called not boring, only if there is a unique number in each successive subsequence,

## [PAT Level] 1043 IS IT A Binary Search Tree (25 points) (Judge whether or not the BST is traversed and outputs traversal traversal)

Title:

Enter a positive integer N (<=1000), and then enter the serial number of N points. If the sequence just entered is a binary search tree or its mirror image (the center is flipped 180°)

## Array – How to use any () on a multidimensional array?

I’m testing an arbitrarily large, arbitrarily sized logical array, and I want to know if one or more of them are true. any() can only be in one dimension at a time Works, so does sum(). I know I ca

## Data Structure and Algorithm – Arrange

An array is a data structure composed of a collection of elements of the same type, and a contiguous memory is allocated for storage. The index of the element can be used to calculate the storage a
