dx

两两枚举点（xi,yi）（xj,yj）对于第三个点（xk,yk），只要向量ik和ij方向不同即可 只要(xj-xi,yj-yi) 和 (xk-xi,yk-yi)化简后不相同即可，用每个点开个map存下一个gcd的pair即可 #include<bits/stdc++.h> using namespace std; #define N 2005 map<pair<int,int>,int>mp[N]; pair<int,int>p[N]; int n; int main(){ cin>>n; for(int i=1;i<=n;i++){ int x,y; scanf("%d%d",&x,&y); p[i]=make_pair(x,y); } for(int i=1;i<=n;i++) for(int j=1;j<=n;j++)if(i!=j){ int dx=p[j].first-p[i].first; int dy=p[j].second-p[i].second; if(dx==0||dy==0){ if(dx)dx=1;if(dy)dy=1; mp[i][make_pair(dx,dy)]++; } else { int d=__gcd(dx,dy); mp[i][make_pair(dx/d,dy/d)]++; } } long long ans=0; for(int i=1

Does anyone know of any documentation for dx? In particular I am interested in knowing what the --core-library option does. Can anybody shed any light on that? This is a special purpose flag that is only used when building some of the framework jars (core.jar, framework.jar, etc.). Normally, dx will refuse to process any java.* or javax.* classes. So this option is used for core.jar, where all those classes are actually defined. Here's a relevant blurb from the dx source (dalvik/dx/src/com/android/dx/command/dexer/Main.java), that gets printed if you try to include a java.* or javax.* class in

I'm going to edit Opera Mini v6.5 server because it is blocked in our country. Now I have unpacked the .apk file extracted classes.Dex then converted it via dex2jar.bat, now modified the server. My problem is I want to repack the .jar or .class to classes.Dex. How do I do it? Here is a solution that was helpful in my case... Suppose .jar file sits in "c:\temp\in.jar". In command prompt window cd to ..\android-sdk\platform-tools. To get .apk execute: dx --dex --output="c:\temp\app.apk" "c:\temp\in.jar" To get .dex file execute: dx --dex --output="c:\temp\dx.dex" "c:\temp\in.jar" For mac, the dx
