vector中的remove的作用是将等于value的元素放到vector的尾部,但并不减少vector的size vector中erase的作用是删除掉某个位置position或一段区域(begin, end)中的元素,减少其size list容器中的remove 成员函数,原型是void remove (const value_type& val); 他的作用是删除list中值与val相同的节点,释放该节点的资源。
Example 1: Create New Vector without NA Values Example 2: Remove NA within Function via na.rm Video & Further Resources With that, let’s do this: Creation of Example Data In the two examples of this R tutorial, I’ll use the followingvector: ...
modCount是Vector对象持有的一个int变量,它本身位于Vector的父类AbstractList中,此处增加1,表示Vector的元素状态发生改变,迭代器那里会使用fail-fast,防止多线程下即遍历又删除,也防止单线程下,一边遍历元素、一边删除元素 2、检查下标是否存在元素 检查传入的下标index是否存在元素,当index与elementCount相等或者大于element...
/* 思路:利用distance和remove函数实现 时间复杂度O(n),空间复杂度O(1) */ class Solution2 { public: int removeElement(vector<int>& nums, int val) { return distance(nums.begin(), remove(nums.begin(), nums.end(), val)); } };
Removes the first (lowest-indexed) occurrence of the argument from this vector. If the object is found in this vector, each component in the vector with an index greater or equal to the object's index is shifted downward to have an index one smaller than the value it had previously. ...

说明:Removes from thelistcontainer either a single element (position) or a range of elements ([first,last)).This effectively reduces the containersizeby the number of elements removed, which are destroyed.以iterator为单元,对元素进行清除。
