LeetCode Remove Element

标签：

Given an array and a value, remove all instances of that value in place and return the new length.

The order of elements can be changed. It doesn‘t matter what you leave beyond the new length.

题意：去除掉指定的数，并返回新数组的长度。其中新数组的元素顺序可以改变。。

思路：简单题，和上一道差不多。

class Solution {
public:
    int removeElement(int A[], int n, int elem) {
        int len = 0;
        for (int i = 0; i < n; i++) {
            if (A[i] != elem) 
                A[len++] = A[i];
        }
        return len;
    }
};
