Create Binary Tree from a List of Values in Python
Run and Try: https://repl.it/@VinitKhandelwal/create-binary-tree
class Node():
def __init__(self, value, left=None, right=None):
self.value = value
self.left = left
self.right = right


class BinaryTree():
def __init__(self, mylist):
self.mylist = mylist
self.root=Node(None)
for value in self.mylist:
self.curr=self.root
self._add(value)
def _add(self, value):
if self.curr.value == None:
self.curr.value = value
else:
if self.curr.value > value:
if self.curr.left == None:
self.curr.left = Node(value)
else:
self.curr = self.curr.left
self._add(value)
else:
if self.curr.right == None:
self.curr.right = Node(value)
else:
self.curr = self.curr.right
self._add(value)

obj = BinaryTree([20,10,30])

print("Root Value: {}".format(obj.root.value))
print("Root's left Value: {}".format(obj.root.left.value))
print("Root's right Value: {}".format(obj.root.right.value))

Output

Root Value: 20
Root's left Value: 10
Root's right Value: 30

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

Resolve: Uncaught TypeError: firebase.database is not a function

If you are getting the error: Uncaught TypeError: firebase.database is not a function Resolve it by including firebase-database.js in your html page as follows: <!-- The core Firebase JS SDK is always required and must be listed first --> <script defer src = "https://www.gstatic.com/firebasejs/6.2.4/firebase-app.js" ></script> <script defer src = "https://www.gstatic.com/firebasejs/3.1.0/firebase-database.js" ></script> That is it. Let me know if this was helpful.
