【CodeForces - 764B 】Timofey and cubes (模拟)

發(fā)布時(shí)間:2023/12/10 编程问答 29 豆豆
生活随笔 收集整理的這篇文章主要介紹了 【CodeForces - 764B 】Timofey and cubes (模拟) 小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

題干:

Young Timofey has a birthday today! He got kit of?n?cubes as a birthday present from his parents. Every cube has a number?ai, which is written on it. Timofey put all the cubes in a row and went to unpack other presents.

In this time, Timofey's elder brother, Dima reordered the cubes using the following rule. Suppose the cubes are numbered from?1?to?n?in their order. Dima performs several steps, on step?i?he reverses the segment of cubes from?i-th to?(n?-?i?+?1)-th. He does this while?i?≤?n?-?i?+?1.

After performing the operations Dima went away, being very proud of himself. When Timofey returned to his cubes, he understood that their order was changed. Help Timofey as fast as you can and save the holiday?— restore the initial order of the cubes using information of their current location.

Input

The first line contains single integer?n?(1?≤?n?≤?2·105)?— the number of cubes.

The second line contains?n?integers?a1,?a2,?...,?an?(?-?109?≤?ai?≤?109), where?ai?is the number written on the?i-th cube after Dima has changed their order.

Output

Print?n?integers, separated by spaces?— the numbers written on the cubes in their initial order.

It can be shown that the answer is unique.

Examples

Input

7 4 3 7 6 9 1 2

Output

2 3 9 6 7 1 4

Input

8 6 1 4 2 5 6 9 2

Output

2 1 6 2 5 4 9 6

Note

Consider the first sample.

  • At the begining row was [2,?3,?9,?6,?7,?1,?4].
  • After first operation row was [4,?1,?7,?6,?9,?3,?2].
  • After second operation row was [4,?3,?9,?6,?7,?1,?2].
  • After third operation row was [4,?3,?7,?6,?9,?1,?2].
  • At fourth operation we reverse just middle element, so nothing has changed. The final row is [4,?3,?7,?6,?9,?1,?2]. So the answer for this case is row [2,?3,?9,?6,?7,?1,?4].
  • 解題報(bào)告:

    ? ?直接模擬,分n的奇偶兩種情況。找一下樣例的規(guī)律就出來(lái)了。。。

    AC代碼:

    #include<bits/stdc++.h>using namespace std; int a[200000 + 5]; int main() {int n;cin>>n;for(int i = 1; i<=n; i++) cin>>a[i];printf("%d",a[n]);if(n%2==1) {for(int i = 2; i<=n; i++) {if(i%2==0) printf(" %d",a[i]);else printf(" %d",a[n-i+1]);}}else {for(int i = 2; i<=(n/2); i++) {if(i%2==0) printf(" %d",a[i]);else printf(" %d",a[n-i+1]);}for(int i = (n/2) + 1; i<=n; i++) {if(i%2==1) printf(" %d",a[i]);else printf(" %d",a[n-i+1]);}}return 0 ; }

    ?

    總結(jié)

    以上是生活随笔為你收集整理的【CodeForces - 764B 】Timofey and cubes (模拟)的全部?jī)?nèi)容,希望文章能夠幫你解決所遇到的問(wèn)題。
