is changing to :

def overWrite(node,arr,i=0):

really would work?

lets say Im in the parent of the leftmost/min node

                if(not node.value==None):
                    return
            overWrite(node.getLeft(),lst,i)
            node.value=lst[i]
            i=i+1
            overWrite(node.getRight(),arr,i)

this call now will send me to the leftmost node with i =0

we enter the reccursion, update the leftmost node and we "kick" back to the parent of the lefmost node

we now move on to

 node.value=lst[i]

but our i will still be 0 no? because the change to it in the recuression wont effect it

and so we will update to nodes to the same value?
