Value passing between winform forms, winform form
1. Constructor
Features: The data is one-way (values cannot be transferred to each other). The simple implementation code is as follows: int value1; string value2; public Form2 (int value1, string value2) in Form Form2) {InitializeComponent (); this. value1 = value1; this. value2 = value2;} in the form Form1, call new Form2 (111, "222 "). show (); // in this way, the 111, "
See Ucenter when there is a function call_user_func, think not its solution, because I thought it is the function of their own definition, the results can not be found everywhere, and then Baidu a bit to know Call_user_func is built-in function, This function allows the user to call directly write functions and pass in a certain parameter, is not very powerful, summarize, write to this log inside it.Let's start with someone else's example:The Call_user_func function is similar to a particular me

Title DescriptionIn an array of integers, an integer that is subscript I, if it is greater than all of its adjacent integers, or is less than all of its adjacent integers, is called the extremum point.Input requirementsThere is 2xn+1 line input: The first line is the number of arrays to be processed n; for the remaining 2xn rows, each 2 rows represents an array. The first line is the number of elements in this array K (4≤k≤80), and the second row is the K integer.Output requirementsThe output is

Description
For an integer whose subscript is I, if it is greater than all its adjacent integers or less than all its adjacent integers, this integer is called an extreme point, the subscript of the extreme point is I.
Input
There are 2 × n + 1 rows of input: the first row is the number of arrays to b
. ConstructorFeatures: it is easy to transmit values in one way (values cannot be transferred to each other ).The implementation code is as follows:In form form2Int value1;String value2;PublicForm2 (INT value1, string value2){Initializecomponent ();This. value1 = value1;This. value2 = value2;}This is called in form form1.New form2 (111, "222"). Show ();// In this way, the 111, "222", these two values are tr
The title contains the shortest length of a sequence of all the given n DNA fragments . DP problem on a bare ac automaton.
Dp[s][u] indicates that the set of DNA fragments already contained is S, and that the current suffix state is the shortest length of the first U node of the automaton.
Dp[0][0]=0

When I look at the UCenter, there is a function call_user_func, which is puzzling, because I thought it was a self-defined function and the results were not found everywhere, later, Baidu learned that call_user_func is a built-in function called call_user_func, which is similar to a special method to call a function. the usage is as follows:
Copy codeThe code is as follows:
Function a ($ B, $ c)
{
Echo $ B;
Echo $ c;
}
Call_user_func ('a, "111", "222
The following is a detailed analysis of the method of invoking user-defined functions in PHP, the need for friends can come to the reference
Let's take the example first:The Call_user_func function is similar to a particular method of calling a function, using the following method:
function A ($b, $c) { echo $b; echo $c; } Call_user_func (' A ', "111", "222"); Call_user_func (' A ', "333", "444"); Display 111
Php custom functions call_user_func and call_user_func_array. The call_user_func function is similar to a special method for calling a function. use the following method: Copy the code: functiona ($ B, $ c) {echo $ B; echo $ c ;} call_user_func (a, 111 call_user_func function is similar to a special method to call a function. the usage is as follows:
The code is as follows:
Function a ($ B, $ c){Echo $ B;Echo $ c;}Call_user_func ('a, "111", "222 ")
