If a row is taken from one table and put in another table, the following error occurs: the row already belongs to another table. To solve the problem, use the following method.Datatable dt = new datatable ();Dt = Ds. Tables ["all"]. Clone (); //

Description
People in the tomskaya region like magic formulas very much. You can see some of them below.
Imagine you are given a sequence
// Define a pointer variable, which is similar to defining an integer variable. It also includes three parts: data type variable name = initial value// Only the pointer variable is used to store the address.// Int * pointer variable type, P pointer
// Int A = 010 + 10; // 0 starts with octal.// 0b starts with binary// 0x starts with hexadecimal// Printf ("% d", a); // % d print a decimal integer.// % X print hexadecimal. (lowercase letters) % x print hexadecimal (uppercase letters)// % O print
// When an array is used as a parameter, you can pass in the array name by calling the function.
# Import "function. H"Int Var = 10; // global variable, which can be accessed in all functions. The space is not recycled during the program running.
// ++, Auto-increment by 1. --, Auto minus 1;// ++, --, Before the variable, first participate in the calculation, then ++ ,--// ++, --, After the variable, first ++, --, and then involved in the calculation

Best naming practices in specific scenarios
Namespace
Pascalcasing should be used to separate the parts of the namespace with dots.Such as microsof. Office. PowerPoint
Use the company name as the namespace prefix to avoid using the

Note
Note is undoubtedly the fastest way to let others know your code as quickly as possible, but the purpose of writing a comment is not just to "explain what the code has done ", more importantly, try to help the code reader understand the code
Given a, B, c, you shoshould quickly calculate the result of a ^ B mod C. (1
Input
There are multiply testcases. Each testcase, there is one line contains three integers A, B and C, separated by a single space.
Output
For each testcase, output an
