3.上面两种方法都使用了Python的特性:自动补齐和index。更常用的方法是两个指针,使用swap而不是删除,将值为val的元素往后放,最后返回前不重复元素的长度即可。这种方法在实现是遇到了些小问题,继续想想。 代码1 classSolution(object):defremoveElement(self, nums, val):""":type nums: List[int] :type val:...

Method-1: remove the first element of a Python list using the del statement One of the most straightforward methods to remove the first element from a Python list is to use thedelstatement in Python. Thedelstatement deletes an element at a specific index. ...
Java List在进行remove()方法是通常容易踩坑,主要有一下几点 循环时:问题在于,删除某个元素后,因为删除元素后,后面的元素都往前移动了一位,而你的索引+1,所以实际访问的元素相对于删除的元素中间间隔了一位。 几种常见方法 1.使用for循环不进行额外处理时(错误) ...
