Hi Prakhar, excellent explainantion as all ways!!!
I had a doubt regarding one test case for this question

[14, 30, 29, 49, 3, 23, 44, 21, 26, 52]
Output:
2
Expected:
-1

Should not be the answer for this test case be 2? because there exists a subarray with [30, 29] which has a difference 1 (similar to the second given test case)
