# 拆分数组并将第一部分添加到末尾 > 原文： [https://www.geeksforgeeks.org/split-array-add-first-part-end/](https://www.geeksforgeeks.org/split-array-add-first-part-end/) 有一个给定的数组，并将其从指定位置拆分，然后将数组的第一部分加到末尾。  **示例**： ``` Input : arr[] = {12, 10, 5, 6, 52, 36} k = 2 Output : arr[] = {5, 6, 52, 36, 12, 10} Explanation : Split from index 2 and first part {12, 10} add to the end . Input : arr[] = {3, 1, 2} k = 1 Output : arr[] = {1, 2, 3} Explanation : Split from index 1 and first part add to the end. ``` **简单解决方案** 我们一对一旋转数组。 ## C++ ```cpp // CPP program to split array and move first // part to end. #include <bits/stdc++.h> using namespace std; void splitArr(int arr[], int n, int k) {     for (int i = 0; i < k; i++) {         // Rotate array by 1\.         int x = arr[0];         for (int j = 0; j < n - 1; ++j)             arr[j] = arr[j + 1];         arr[n - 1] = x;     } } // Driver code int main() {     int arr[] = { 12, 10, 5, 6, 52, 36 };     int n = sizeof(arr) / sizeof(arr[0]);     int position = 2;     splitArr(arr, 6, position);     for (int i = 0; i < n; ++i)         printf("%d ", arr[i]);     return 0; } ```
