Given an array A containing N numbers. The problem is to find the minimum gcd among all non-decreasing subarrays. Note: Gcd of k number is the greatest number which divides all k numbers. Example 1: Input : arr[] = {1, 2, 3, 2, 4, 1, 7} Output : 1 Explanation : Some non decreasing subarrays are - {1, 2, 3} gcd = 1, {2, 4} gcd = 2, {1, 7} gcd = 1, minimum gcd = 1
