力扣——remove element(删除元素) python实现 题目描述: 中文: 给定一个数组 nums 和一个值 val,你需要原地移除所有数值等于 val 的元素,返回移除后数组的新长度。 不要使用额外的数组空间,你必须在原地修改输入数组并在使用 O(1) 额外空间的条件下完成。 元素的顺序可以改变。你不需要考虑数组中超出新长度后面...

[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...
