Erase() function to remove a single and specific element from a vectorerase() method can be used to remove a single element by passing the position or with the help of index. Here we have discussed all the meth
To remove elements in a vector based on a condition Iterate over the elements of given vector using index. If the condition is satisfied, delete the current element. Examples 1. Remove negative numbers from vector In the following program, we take an integer vector inv, and remove the negativ...
2.2 实现代码 /* 思路:遍历vector的所有项,分别与val比较 相同: index不加,nums[i] 赋值给nums[index] 不相同:index加1,不需要赋值 时间复杂度O(n),空间复杂度O(1) */ class Solution { public: int removeElement(vector<int>& nums, int val) { int index = 0; for (size_t i = 0; i < n...
true if the argument was a component of this vector; false otherwise. Attributes RegisterAttribute Remarks 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...

2.1 std::find:查找单一元素(Searching for a Single Element) std::find是一个用于在容器中查找单一元素的算法。它接受两个迭代器(表示搜索范围的开始和结束)和一个值,然后返回一个指向找到的元素的迭代器。 #include <algorithm>#include <vector>#include <iostream>int main() {std::vector<int> vec = ...
In this example, the third argument of thefind()function is used with the string'last'to set the direction of searching from the last element towards the first. Consequently, the last two zero values are removed from the vectorn. Output: ...
