C++ Program to Split the array and add the first part to the end
There is a given an array and split it from a specified position, and move the first part of array add to the end.
Examples:
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.
// 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; } |
Output:
5 6 52 36 12 10
