class Solution { public int removeElement(int[] nums, int val) { int i=0,j=nums.length-1;//i-左指针;j-右指针 while (i<=j){ if(nums[i]==val){ nums[i]=nums[j];//得到索引j的值,无需把索引j的值改为索引i的值 j--; }else i++; } return j+1; } } Python3: 代码语言:...
27. Remove Element(python3) 27. Remove Element Easy Given an array nums and a value val, remove all instances of that value in-placeand return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory...

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。
