Sort a linked list using insertion sort. 因为是single linked list, 要从前面往后面检查。 引用一个pre, 每次检查pre。next, 比较大小,如果小了,就插在pre后面。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
The simplest method to get the shape of a list in Python is by using thelen()function. It provides the length (number of elements) of a list, effectively giving the size of the first dimension. Thelen()function has a simple and concise syntax: ...
本文实例讲述了php中get_cfg_var()和ini_get()的用法及区别。分享给大家供大家参考。具体分析如下: php里get_cfg_var()和ini_get()都是取得配置值的函数,当你需要获取php.ini里的某个选项的配置值时,这两个函数都都可以使用,得到的结果是一样的。不过,get_cfg_var()和
