To find the minimum element from a sorted and rotated array, we can use a binary search approach.Start by initializing two pointers, 'start' and 'end', representing the start and end indices of the array.Perform the binary search until 'start' < 'end'.If 'arr[start]' < 'arr[end]', it means the array is not rotated, so the smallest element is 'arr[start]' and we return it.
