(LeetCode)Remove Element --- 去掉指定元素
来源:互联网 发布:snap.svg.js实例教程 编辑:程序博客网 时间:2024/05/19 06:48
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 in place with constant memory.
The order of elements can be changed. It doesn't matter what you leave beyond the new length.
Example:
Given input array nums = [3,2,2,3]
, val = 3
Your function should return length = 2, with the first two elements of nums being 2.

解题分析:先计数,然后再去掉count个的指定val。
