The compiling principle is basically divided into the following points in the test center of soft examinations: grammar, grammar, tree and operator precedenceHere is a summary of these three aspects. Grammar Basic ElementsThe first thing to understand is the two most basic elements of grammar: non-terminator and Terminators.Non-Terminator can be understood as elements that can also be split, generally in uppercase letters, terminator of course can be seen as an element that cannot be split, Term

Android SDK has been integrated with this software. You need to find it and install it. Put his location in this directory: Of course, your location may be different. If you cannot find it, there is no need to crash development. If the problem is solved in this way, it would be too pediatric. When I double-click the installation, the problem comes again: this computer meets the requirements for haxm but intel virtualization technology（VT-x） is not

Note that the swap takes place one at a time.Swap, is for both stickers, only occurs in one sticker a friend has a quantity of 0, while another friend has more than 1.So the map, for each friend, if the sticker number is 0, then this sticker to this friend with a c
