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.

Algorithm – Quicksort: iteration or recursive
I learned about quick sorting and how to implement it in recursive and iterative methods.
In iterative methods:
>The range (0 … N) Push onto the stack
>Use a pivot table to partition a given

Friend HDU-1719 Friend number are defined recursively as follows.
(1) numbers 1 and 2 are friend number;
(2) if a and b are friend numbers, so is ab+a +b;
(3) only the numbers defined in (1
