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。

Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: std::string for strings, int64_t, uint64_t or double for numbers, std::map for objects, std::vector for ...
