A text return is a string that is the same as reading and reading. For example, level and eye are all input files. The iterative method can be used to quickly determine whether a string is a return object. How can we implement it using recursive

Backup: The table structure and data are completely separated, the default one file will record all the structure of the table, and then the data in the table backup if the size of the volume will be divided into multiple files, or a file, referring

When learning to program, teachers always do not recommend recursion, some books have so far suggested. But the application of recursion in binary tree is graceful and slightly complicated. So it is necessary to understand that the nature of

Whether recursion hides the loop first look at the code function reverse($str){ if(strlen($str)>0){ reverse(substr($str,1)); echo substr($str,0,1); return; }}reverse("abcdefg");//gfedcbc In the above example, I think it means a loop.
