vector的find方法

vector的find方法存在于<algorithm>头文件中。你可以使用find函数来查找vector中是否存在某个特定的元素。下面是一个示例代码：

#include <vector>
#include <algorithm>
#include <iostream>
using namespace std;

int main() {
    vector<int> L;
    L.push_back(1);
    L.push_back(2);
    L.push_back(3);
    
    vector<int>::iterator it = find(L.begin(), L.end(), 3);
    
    if(it == L.end())
        cout << "NO" << endl;
    else
        cout << "YES" << endl;
}

在这个例子中，我们定义了一个vector L，然后使用find函数来查找值为3的元素。如果找到了，输出YES，否则输出NO。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
