kandi X-RAY | CodeBot Summary
CodeBot is a chatbot that helps beginners learn how to code. To make the otherwise daunting task of learning how to code for the first time easier, CodeBot incorporates witty replies, GIFs & human-readable errors to create an incredibly fun experience for a complete novice. Currently, it goes through a few elementary exercises in Python (adapted from Codecademy) while answering user questions using basic NLP. The back-end runs on Node.js, MongoDB & api.ai while the front-end is written in vanilla HTML, CSS & JavaScript.

QUESTION
After becoming famous, the CodeBots decided to move into a new building together. Each of the rooms has a different cost, and some of them are free, but there's a rumour that all the free rooms are haunted! Since the CodeBots are quite superstitious, they refuse to stay in any of the free rooms, or any of the rooms below any of the free rooms.
Given a matrix, a rectangular matrix of integers, where each value represents the cost of the room, your task is to return the total sum of all rooms that are suitable for the CodeBots (ie: add up all the values that don't appear below a 0).
Example: for:

QUESTION
I am working through some algorithm challenges to get some more Python practice. I am having some problems with a problem that requires changing values inside a python matrix (list of lists).
...ANSWER
Answered 2019-Jan-11 at 18:26You are still going to require nested for loops in some fashion or another since you are iterating over a list of lists, but you could simplify the logic a bit using list comprehensions.
QUESTION
I have a bot with a root LuisDialog and 4 more LuisDialogs each one with a different LUIS model. Following the conversation started here I've implemented a similar DialogFactory strategy.
When a user sends a question that matches "None" intent in my root dialog, I evaluate the rest of dialogs until I find a match and then forward the message to the "winner".
The problem I'm facing is that I'm getting the http error: 429 (Too Many Requests) when querying LUIS (BaseDialog class).
Any ideas about how to face this?
The "None" intent in my root dialog:
...ANSWER
Answered 2017-Nov-08 at 11:47The 429 error is caused by your application (key) hitting the LUIS API too heavily.
You need to either throttle your requests to ensure you stay below the threshold of the free tier, or upgrade to the Basic plan which allows 50 requests a second.
QUESTION
I'm working on Java via the Codefights website. This is the exercise:
After becoming famous, CodeBots decided to move to a new building and live together. The building is represented by a rectangular matrix of rooms, each cell containing an integer - the price of the room. Some rooms are free (their cost is 0), but that's probably because they are haunted, so all the bots are afraid of them. That is why any room that is free or is located anywhere below a free room in the same column is not considered suitable for the bots. Help the bots calculate the total price of all the rooms that are suitable for them. Example: For
