本文介绍了一个C++ STL向量中移除指定值的实现方法，并对其进行了简单的性能说明。 
class Solution {
public:
    int removeElement(vector<int>& nums, int val) {
        vector<int>::iterator it=nums.begin();
        while(it != nums.end()){
            if(*it == val){
                it = nums.erase(it);
            }
            else
                it++;
        }
        return nums.size();
    }
};

没什么好说的，就是速度咋这么慢？
