The execution of make relies on a makefile file that tells make how it should perform the compile and link operations. make determines which files need to be updated by comparing the last modification time of the corresponding file . The Make tool

There are a lot of cross-domain solutions, and jquery is good at it, and now HTML5 is starting to support cross-domain, but now HTML isn't universal. So is there a simple way to solve cross-domain problems in the case of a parent-child domain?

The problem is the so-called "maximum as small as possible" typical representative, the method is to guess the most value with two points, the judging function is the former sweep, as far back as possible, if the final number of groups smaller than

Main topic:Very simple, just need to find the maximum depth of a binary tree, it seems that there is no time and space requirements.Solution Method:More simple, only need to follow the width first method to find, here I use a queue to save the node
