see, but I noticed that this wireless chip model is Realtek Rtl8188cus, the initial suspicion is the driver problem.Of course, see someone else's old wireless network card has been configured successfully in the heart unavoidably itch, of course, also can not waste money to buy a network card, so had to find their own, but despair, in the N-time brush machine reload system, finally found a successful approach, in fact, the key article on the above article in a link in the Turn Your Raspberry Pi
This article is based on the purchase of a East USB wireless network card (Rtl8188cus chip) to make wireless hotspot. Originally wanted to make a one-click script. Just record the implementation process first.

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

The first step is to open the Excel document:

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.

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.
