Given a m x n Matrix, if an element was 0, set its entire row and column to 0. Do it on place.Follow up:Did you use extra space?A straight forward solution using O (mn) space is probably a bad idea.A Simple Improvement uses O (m + n) space, but still is not the best solution.Could you devise a constant space solution?Problem: Given a matrix, when the matrix has an element of 0, the current row of that element is set to 0.My solution meets the supplemental content of the 2nd, using O (M + N) extr

Java record-73-generic detailsNew features in JDK5.0: Generic (Generics); Enhanced "for" loop (Enhanced For loop); Autoboxing/unboxing ); type safe enums, Static import, Var args, and generic are one of the most important features in JDK1.5. By introducing generics, we will be able to get the possibility of throwing ClassCastException with a lower type of security and runtime during compilation. If you use generics, as long as the Code does not have a

Examples are as follows:Androidhttpclient httpClient = androidhttpclient.newinstance("my-http-agent-string");The parameter that is taken is the HTTP request message header user-agent. For example, in the last study we showed the contents of the User-agent message header by grabbing a packet:dalvik/1.6.0 (Linux; u; Android 4.2.2; SDK build/jb_mr1.1)Once we have created the Androidhttpclient in

Recommendation 73: Avoid locking inappropriate synchronization objectsIn C #, another way to encode thread synchronization is to use the thread lock. The principle of the thread lock is that it locks a resource so that the application has only one thread to access it at the moment. In layman's words, it makes multithreading a single thread. In C #, a locked resource can be understood as a new normal CLR object.Since the resource that needs to be locke
