[Leetcode][python]Remove Element/移除元素 题目大意 去掉数组中等于elem的元素,返回新的数组长度,数组中的元素不必保持原来的顺序。 解题思路 双指针 使用头尾指针,头指针碰到elem时,与尾指针指向的元素交换,将elem都换到数组的末尾去。 代码 判断与指定目标相同...
This way we can use thedelstatement to remove the first element of the Python list. Method-2: Remove the first element of the Python list using the pop() method Thepop()method is another way to remove an element from a list in Python. By default,pop()removes and returns the last ele...
