Description

Little Petya very much likes gifts. Recently he has received a new laptop as a New Year gift from his mother. He immediately decided to give it to somebody else as what can be more pleasant than giving somebody gifts. And on this occasion he organized a New Year party at his place and invited n his friends there.

If there's one thing Petya likes more that receiving gifts, that's watching others giving gifts to somebody else. Thus, he safely hid the laptop until the next New Year and made up his mind to watch his friends exchanging gifts while he does not participate in the process. He numbered all his friends with integers from 1 to n. Petya remembered that a friend number i gave a gift to a friend number pi. He also remembered that each of his friends received exactly one gift.

Now Petya wants to know for each friend i the number of a friend who has given him a gift.

Input

The first line contains one integer n (1 ≤ n ≤ 100) — the quantity of friends Petya invited to the party. The second line contains nspace-separated integers: the i-th number is pi — the number of a friend who gave a gift to friend number i. It is guaranteed that each friend received exactly one gift. It is possible that some friends do not share Petya's ideas of giving gifts to somebody else. Those friends gave the gifts to themselves.

Output

Print n space-separated integers: the i-th number should equal the number of the friend who gave a gift to friend number i.

交换礼物, 排一下编号。

代码:

#include <iostream>
#include <cstdlib>
#include <cstdio>
#include <cstring>
using namespace std;

const int N = 10000 + 100;

int main()
{
    int n;
    while(scanf("%d", &n) != EOF)
    {
        int *a = new int[n+10];
        memset(a, 0, sizeof(a));
        int tmp;
        int cnt = 0;
        for(int i = 1; i <= n; i++)
        {
            scanf("%d", &tmp);
            a[tmp] = ++cnt;
        }
        for(int i = 1; i < n; i++)
        {
            printf("%d ", a[i]);
        }
        printf("%d\n", a[n]);
    }
    return 0;

WebSocket是一种在客户端和服务器之间建立持久连接的协议,它允许双方进行双向通信,极大地提高了实时性,被广泛应用于即时通讯、在线游戏、股票交易等领域。本篇将详细讲解如何使用C#来实现WebSocket,以及Fleck库在其中的作用。 WebSocket协议基于HTTP的握手过程,但一旦连接建立,它就不再依赖HTTP,而是通过TCP直接通信。在C#中,我们可以利用.NET Framework或.NET Core提供的System.Net.WebSockets命名空间来创建WebSocket服务器和客户端。然而,对于更高级的功能和更好的灵活性,开发者通常会选择第三方库,如Fleck。 Fleck是C#中一个轻量级且高效的WebSocket服务器实现。它提供了丰富的事件驱动API,使得开发者可以轻松地处理WebSocket连接的建立、消息传递和断开等操作。下面我们将探讨Fleck的使用步骤: 1. **安装Fleck**:你需要在你的项目中添加Fleck库。如果你使用的是NuGet包管理器,可以通过搜索"Fleck"并安装来获取。 2. **初始化服务器**:在C#代码中,首先创建一个Fleck服务器实例,指定监听的IP地址和端口号。例如: ```csharp var server = new Fleck.WebSocketServer("ws://localhost:8080"); ``` 3. **配置服务器**:你可以设置各种配置选项,如最大接收/发送缓冲区大小、心跳间隔等。然后注册事件处理器,如OnOpen、OnClose、OnMessage等,以处理客户端连接、断开和消息接收。 4. **连接事件**:`OnOpen`事件在客户端连接时触发,你可以在这里对新连接进行初始化操作,如存储连接信息、验证用户等。 5. **消息处理**:`OnMessage`
