"As far as i know, when we type a web address in the browser-
the broswer connects to the DNS server & finds the address of the website we are looking for
after finding it, the browser sends an HTTP request message to the server,with a request to send a copy of the website to the user.

"A much better solution than the one in the article, below:
It looks like the ones writing articles here in Javascript do not understand the time/space complexity of javascript methods.
shift, splice, sort, etc... In the solution article you have a shift and a sort being done inside a while, that is, the multiplication of Ns.
My solution, below, iterates through the list once and then sorts it, separately. It´s O(N+Log(N))

"The height of a binary tree is the maximum number of edges from the root node to any leaf node. To calculate the height of a binary tree, we can use a recursive approach. The basic idea is to compare the heights of the left and right subtrees of the root node, and return the maximum of them plus one."

"Questions:
Can the toothbrush be a smart toothbrush, different from typical toothbrushes? Ans: Yes
Children's age group? Ans: Pick your choice

"Wing is a subsidiary of Alphabet that provides technology for drone delivery of freight.
Current pain points :
Noise level when drones are flying
Competitive landscape in terms of traffic management system
Broadcast network IDs to identify the recipient - privacy concern
Considering that privacy concern is a large issue by itself and traffic management system is something I assume Wing would have plans for the future, Idea would be work on the noise level as a recently joined PM.
