There are ‘N’ numbers of balls in a room that are placed in a row. You are given an array ‘location’ where location[ i ] denotes the location of the ‘i-th’ ball.

You have to move all the balls at the same location, and it is given that you can move a ball from position [ i ] to

1. position[i] + 2 with cost = 0.

2. position[i] + 1 with cost = 1.

Your task is to find the minimum cost required to move all the balls at the same location.

For Example :

If we have three balls placed at [ 1, 3, 4 ]

At first, move the ball from position ‘1’ to position ‘3’ with cost = 0.
Then move the ball from position ‘4’ to position ‘3’ with cost =1.
As the minimum cost = 1, so you need to print 1.

You have been given a Singly Linked List of integers, determine if it forms a cycle or not. If there is a cycle, remove the cycle and return the list.

A cycle occurs when a node's ‘next’ points back to a previous node in the list.

You are given an array containing 'N' points in the plane. The task is to find out the distance of the closest points.

Note :

Where distance between two points (x1, y1) and (x2, y2) is calculated as [(x1 - x2) ^ 2] + [(y1 - y2) ^ 2].
