This post will discuss how to remove an element from the end of a vector in C++. The solution should effectively reduce the vector size by one.
//removes the element 'java' which appears multiple times in the vector vector1.erase(remove_if(vector1.begin(),vector1.end(),rmv::remove("Java")),vector1.end()); // Printing the vector cout<<"\nAfter Removing elements vector is:"; for (auto it = vector1.begin(); it != vector...

/* 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. ...

Usestd::eraseandstd::removeFunctions to Remove Element From an Array in C++ Another scenario for this problem occurs when the given array is of typestd::vector. This time, we have the dynamic array features, and it’s more flexible to use a built-in function for element manipulations. ...
返回值:An iterator pointing to the element that followed the last element erased by the function call. This is thecontainer endif the operation erased the last element in the sequence. remove: 说明:Remove elements with specific value。Removes from the container all the elements that compare equal...
