WebIn each recursion we can obtain a new head and a new tail (i.e. the original head of that sub-list). Then we can join that tail with the original head of the upper level, and the original head of the upper level becomes the new tail. Calling this procedure recursively allows us to reverse the entire linked list. Complexity analysis Time complexity
