Post Order Traversal Binary Search Tree Like 3 6 5 1 12 16 15 10 20 7 Want Find Pre Order Q43883209
I have a post-order traversal of a Binary Search Tree like[3,6,5,1,12,16,15,10,20,7] and I want to find its pre-ordertraversal like [7,1,5,3,6,20,10,15,12,16]. I need the Python code.Please solve with constructing tree and the code should be easilyunderstandable and basic, not a sophisticated code (such as withoutusing nested functions). (It should NOT be a recursivesolution)
