Program for printing array in Pendulum Arrangement.
To arrange elements of the array following pendulum arrangement.
- Sort the given array, create an empty array to store the result.
- Store the 0th element in a variable say temp.
- Store the element at index 1 in the sorted array in (mid+1)st position of the resultant array, and the next element int the (mid-1)st position and the next element in (mid+2)nd element and so on.
Example
import java.util.Arrays;
import java.util.Scanner;
public class ArrayinPendulumArrangement {
public static int[] swap(int origPos, int newPos, int[] array){
origPos = 1;
newPos = 4;
int temp = array[origPos];
array[origPos] = array[newPos];
array[newPos] = temp;
System.out.println(Arrays.toString(array));
return array;
}
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
System.out.println("Enter the required size of the array (odd) :");
int size = sc.nextInt();
int [] myArray = new int[size];
System.out.println("Enter elements of the array :");
for(int i = 0; i< size; i++){
myArray[i] = sc.nextInt();
}
//Sort the given array
Arrays.sort(myArray);
System.out.println("Contents of the Array"+Arrays.toString(myArray));
int temp = myArray[0];
int mid = (size-1)/2;
int k =1;
int[] result = new int[size];
for(int i = 1; i<=mid; i++){
result[mid+i] = myArray[k++];
result[mid-i] = myArray[k++];
}
result[mid] = temp;
System.out.println("Pendulum arrangement "+Arrays.toString(result));
}
}Output
Enter the required size of the array (odd) : 5 Enter elements of the array : 12 28 46 77 39 Contents of the Array[12, 28, 39, 46, 77] Pendulum arrangement[77, 39, 12, 28, 46]
