算法题丨Remove Element
描述 Given an array and a value, remove all instances of that value in-place and 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. The order of elements can be changed. It doesn't matter what you leave beyond the new length. 示例 Given nums = [3,2,2,3], val = 3, Your function should return length = 2, with the first two elements of nums being 2. 算法分析 难度:低分析:给定数组和指定一个目标值,从数组中移除所有跟目标值相等的元素,返回最终元素的长度,注意不要...
