Combine the arrays without allocating another array, leaving arr1 in ascending order. Follow-up 1: solve the equivalent task when both inputs are ordered from largest to smallest. Follow-up 2: explain how you would handle arrays that arrive unsorted, including the resulting complexity. Examples The…
