数组元素循环右移问题PTA

以下是C语言和Python两种实现数组元素循环右移问题的例子：

C语言实现：

#include <stdio.h>

void reverse(int arr[], int start, int end) {
    while (start < end) {
        int temp = arr[start];
        arr[start] = arr[end];
        arr[end] = temp;
        start++;
        end--;
    }
}

void rightShift(int arr[], int n, int k) {
    k %= n;
    reverse(arr, 0, n - k - 1);
    reverse(arr, n - k, n - 1);
    reverse(arr, 0, n - 1);
}

int main() {
    int n, k;
    scanf("%d %d", &n, &k);
    int arr[n];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }
    rightShift(arr, n, k);
    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
        if (i != n - 1) {
            printf(" ");
        }
    }
    return 0;
}

Python实现：

nums = input()
L = nums.split(" ")
A, B = int(L[0]), int(L[-1])
B = B % A
numChars = input().split(" ")
Array = [int(i) for i in numChars]
if B > 0:
    Array = Array[::-1]
    leftA = Array[:B][::-1]
    rightA = Array[B:][::-1]
    Array = leftA + rightA
length = len(Array)
for i in range(length):
    print(Array[i], end="")
    if i < (length - 1):
        print(" ", end="")
    i = i + 1
