A title: A two-dimensional array, with a positive number, a negative number, to find its maximum sub-matrix.Two design ideas:This problem is basically no difficulty, because this problem can refer to the previous one to solve the two-dimensional array of sub-matrices (not the end-to-end), so it can be divided into two simple parts. The first step is to turn it into a one-dimensional array (loop), and then s

End-to-end data chapter seventhFrom a network perspective, applications send information to each other. Each message is simply an unexplained string. However, from an application standpoint, these messages contain various types of data-integer arrays, video frames, text lines, digital images, and so on. Therefore, we need to consider how to better encode the different types of data that the application is c

CSS3 of the Times, css3--animation is all possible; The traditional JS can judge whether the animation is finished by the callback function, even if the animation effect is generated by CSS technology, JavaScript can still capture the animated or transformed end event. Transitionend Event and Animationend event standard browser events, but in WebKit browsers you still need to use the WebKit prefix, so we have to detect events based on various brow

Functional is achievable, but there are some flaws, such as the page is too long when the mask layer will also slide with the page, the position of the button will be changed: Solution PC Side The solution of the PC side is to cancel the existing scroll bar when the mask layer is ejected to achieve the effect of not scrolling. That is to add overflow:hidden properties to the body, IE6, 7 will not take effect, you need to add Overflow:hidden attributes to HTML. Solution Mobile

IntroductionNot long ago, industrial standard testing practices (developed for the quality of the C/S architecture) it still focuses on the front-end function test of the client or the backend scalability test and Performance Test of the server. This "Work separation" is mainly due to the fact that the traditional C/S (Client/Server) architecture is relatively simple than the current multi-layer architecture and distributed environment. In the standar

Today, I saw a small program in unix network programming, which is very enlightening. Int check_cpu () {Union {Short;Char B;} C;C. a = 1;Return c. B = 1; } If it is a small-end storage, 1 is returned, and the large-end storage returns 0. I feel that this function is clever and uses the characteristics of union to determine the memory storage format. Union p
