Write a program to input a list of integers in an array and arrange them in a way similar to the to-and-fro movement of a Pendulum.
- The minimum element out of the list of integers, must come in center position of array.
- The number in the ascending order next to the minimum, goes to the right, the next higher number goes to the left of minimum number and it continues.
- As higher numbers are reached, one goes to one side in a to-and-fro manner similar to that of a Pendulum.
Input : 1 3 2 5 4 Output :5 3 1 2 4 Explanation: The minimum element is 1, so it is moved to the middle. The next higher element 2 is moved to the right of the middle element while the next higher element 3 is moved to the left of the middle element and this process is continued. Input : 11 12 31 14 5 Output :31 12 5 11 14
The idea is to sort the array first. Once the array is sorted, use an auxiliary array to store elements one by one.
Pendulum arrangement: 21 14 6 12 19
