第二次过这道题,试了几次才AC,代码如下: classSolution {public:intremoveElement(vector<int>& nums,intval) {if( nums.size()==0)return0;intlast = nums.size()-1;while( nums[last]==val && last>0) last--;for(inti=0; i<=last; ++i ) {if( nums[i]==val ) { std::swap(nums[i]...
iterator erase (const_iterator first, const_iterator last); Removes from the vector either a single element (position) or a range of elements ([first,last)). 而pop_back() 是表示弹出最后一个元素,无参数,无返回值。 vector 的迭代器 或者: 常记溪亭日暮,沉醉不知归路。兴尽晚回舟,误入藕花深处。
