# Approach
The code follows the Sorting + Sliding Window approach.

Step-by-Step Explanation:
Edge Case Handling:

If nums.length < k, return 0 (since it's impossible to pick k elements).
If k == nums.length, sort nums and return nums[nums.length - 1] - nums[0] (max - min of the entire array).
Sorting:

The array is sorted in ascending order to make it easier to pick k consecutive elements with the smallest difference.
Sliding Window (Fixed-size Window of k elements):

Iterate through the array, picking k consecutive elements.
Track the minimum difference between the first and last element of each selected window.
Return the Minimum Difference Found.

# Complexity
- Time complexity: O(NlogN) 
-(dominated by sorting)

<!-- Add your time complexity here, e.g. $$O(n)$$ -->

- Space complexity: O(1) 
-(Sorting is in-place, and only a few extra variables are used)
<!-- Add your space complexity here, e.g. $$O(n)$$ -->

# Code
```java []
import java.util.*;
class Solution {
    public int minimumDifference(int[] nums, int k) {
        if(nums.length<k)
        {
            return 0;
        }else if(k==nums.length){
            Arrays.sort(nums);//ascending order sorting 
            return nums[nums.length-1]-nums[0];
        }else{
            Arrays.sort(nums);//ascending order sorting 
            int min=Integer.MAX_VALUE;
            for(int i=0;i<=nums.length-k;i++)
            {
                int first=nums[i];
                int last=nums[(i+k)-1];
                min=Math.min(min,last-first);
            }
            return min;
        }
    }
}
