1. magnetic stripe wear test
(According to: ISO 7811-2; Test Procedure: ISO/IEC, 10373)
To understand how the magnetic stripe reflects wear, first write the test data into the magnetic stripe, and then use a dumb read/write head. The hardness is 110hv to 130hv and the curvature radius is 10mm, along the magnetic stripe. 5 N of the external force often move times, and then read the data, the signal range must be within the range specified
Test instructions look at me and cry. The English is really poor.The first line goes without saying ... After each line, the next few numbers are the descendants of the first number, and, finally, a possible ancestor to the last order 、。。。。。。。。。。。Topological ordering (the WA code for the first example is just past the sample)#include #include #include #include #include #include #include using namespace Std;int a[2][101][101]={0};int ans[101];int main (){int m;scanf ("%d", m);for (int i=0;i{int q
remaining n lines should each contain a single positive integer (each of the representing an elephant). If these n integers is a[1], a[2],..., a[n] Then it must is the case that W[a[1]] and S[A[1]] > s[a[2] [> ... > S[a[n]]in order for the answer to is correct, n should be as large as possible. All inequalities is strict:weights must is strictly increasing, and IQs must be strictly decreasing. There may is many correct outputs for a given input, and your program only needs to find one.Samp
follows:void Closelog (void);It is worth noting that although the use and invocation of this function is very simple, but is necessary, because in the Linux system, the open log is also a resource, if you only use the Openlog function to open the log, and forget to use Closelog to close the log, when the number of open logs accumulated to a certain extent , it causes insufficient memory, which can cause system problems. Therefore, remind the user to pay special attention in the use.Examples of

There is a length of the whole number of L (1Now to remove some trees, the interval of the removed tree is represented by a pair of numbers, such as 100 200 to remove all trees from 100 to 200 (including the endpoints).There may be an M (1
Input:
Two integer L (1Next there are M-group integers, each with a pair of numbers.
Output:
There may be multiple sets of input data, and for e

Exam aquestion 1Given a Pre-generics implementation of a method:One. public static int sum (List list) {sum of int = 0;for (Iterator iter = List.iterator (); Iter.hasnext ();) {int i = ((Integer) Iter.next ()). Intvalue ();sum = i;16.}return sum;18.}What three changes allow the class to is used with generics avoid and unchecked a warning? (Choose
Three.)
Change which three places allow this class to use gene
all the rows in the Range object. In actual development, a special phenomenon is found in the second method, so the second method is also prepared to describe it in detail.
The first step is to open the Excel document:
Object Filename= "";
Object missingvalue=type.missing;
String Strkeyword= ""; Specifies the text to search for, and if there are more than one, declare string[]
Excel.Application ep=new Excel.applicationclass ();
Excel.Workbook Ew=ep
Find () method of the Range object, and the other a bit cumbersome, After you get the valid area UsedRange of the worksheet worksheet, iterate through all the rows in the Range object. In actual development, a special phenomenon is found in the second method, so the second method is also prepared to describe it in detail.
The first step is to open the Excel document:
Object Filename= "";
Object missingvalue=type.missing;
String Strkeyword= ""; Specifies the text to search for, and if there
achieved through two methods. One is through the Find () of the Range object () method To achieve this. In addition, it is troublesome to retrieve the valid zone UsedRange of the Worksheet and traverse all the rows and columns in the Range object. In actual development, a special phenomenon is found when the second method is used, so the second method is also prepared to be described in detail.
Step 1: Open the Excel document:
Object filename = "";
Object MissingValue = Type. Missing;
