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。
How to delete element from Vector How to delete element from Vector: There is tricky thing for deleting in vector loop. The erase method returns the next element after the one you just erased. So you can use that to continue in your loop. vector c; iterator i = c.begin(); while(i ...

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 ...
