Around 5.31, the teacher says “I’ll only taverse a node only if all its CHILD nodes are traversed”. I think it should be “I’ll only taverse a node only if all its PARENT nodes are traversed”
Please clear if I’m right or I’m missing somethihg.
I think there is a mistake here
Hey @parresh77-g, no there is not any mistake over here. Actually if you would watch the video again, sir has clearly mentioned that the tree is inverted. So when the tree is created, the parent classes are below and child classes are above them. So that is the reason you are getting confused. I would request you to go through the video and listen to the sentence and rule once again !
If you still don’t get it, feel free to create a doubt on the portal anytime !
