SDE - 1

You are given an array 'arr' consisting of 'n' integers which denote the position of a stall.

You are also given an integer 'k' which denotes the number of aggressive cows.

You are given the task of assigning stalls to 'k' cows such that the minimum distance between any two of them is the maximum possible.

Print the maximum possible minimum distance.

Example:

Input: 'n' = 3, 'k' = 2 and 'arr' = {1, 2, 3}

Output: 2

Explanation: The maximum possible minimum distance will be 2 when 2 cows are placed at positions {1, 3}. Here distance between cows is 2.

You are given an array 'a' of size 'n'.

Print the Next Greater Element(NGE) for every element.

The Next Greater Element for an element 'x' is the first element on the right side of 'x' in the array, which is greater than 'x'.

If no greater elements exist to the right of 'x', consider the next greater element as -1.

For example:

Input: 'a' = [7, 12, 1, 20]

Output: NGE = [12, 20, 20, -1]

Explanation: For the given array,

- The next greater element for 7 is 12.

- The next greater element for 12 is 20. 

- The next greater element for 1 is 20. 

- There is no greater element for 20 on the right side. So we consider NGE as -1.
