5. Function (2) – function recursion Original address: https://beryl-licorice-3a8.notion.site/2-024e7053e9e040feae48e95fb13b7164?pvs=4 1. What is recursion? In short, function recursion means that the function calls itself. Function recursion is just a way to solve the problem. #include <stdio.h> int main(){<!– –> printf(“hehe”\ ); main();//The main function is called again in the main function return 0; }//This is a […]
Tag: recursion
PHP uses recursion to integrate its two-dimensional array into a hierarchical tree, where the hierarchical id is in a uuid format. The weird problem has been solved.
No more verbosity, just go directly to the source code. <?php function findChildren($list, $p_id){ $r = array(); foreach ($list as $k => $item) { if ($item[‘fid’] == $p_id) { unset($list[$k]); $length = count($r); $r[$length] = $item; if ($t = findChildren($list, $item[‘id’])) { $r[$length][‘children’] = $t; } } } return $r; } function findChildren2($list,$p_id, & amp;$sike=[]) […]

File class, method recursion
File: represents text IO stream: reading and writing data 1. How does the File class construct objects? What can a File object represent? Notice · File objects can represent both files and folders. ● The object encapsulated by File is just a path name. This path can exist or not exist. 2. What do absolute […]
