WebNov 16, 2016 · 1. I am trying to convert a binary search tree to a linked list. The linked list should have the smaller numbers in the front and the larger numbers in the back (smallest to largest). I need to create a function that takes in a binary search tree tree and outputs a linked list. 4 / \ 2 6 / \ / \ 1 3 5 7. Here's my binary search tree. WebThe time complexity of the above solution is O(n.log(n)), where n is the total number of nodes in the linked list, and the auxiliary space required is O(n) for the merge sort algorithm.. The above solution first flattens the list and then sort it. We can combine both these steps into one step, i.e., sorting the list while flattening it.
