11-30 Exercise 2: Rotated Array

Question

Write a program that reads integers and stores them in an array. Then, the program should rotate the elements one place to the right. For example, if the array were 1, -9, 5, 3, the rotated array would be 3, 1, -9, 5.

寫一個程式 輸入整數放在陣列裡。將陣列裡面的元素向右旋轉一次

Example input 1: First number is the element of array to input, then the list of numbers

4
1 -9 5 3

Example output 1:

3 1 -9 5

 

Example input 2:

5
2 7 9 3 12

Example output 2:

12 2 7 9 3

Please remember, you may correct the cases, but your code always be revised!
