Consider a navigation problem suchas a mechanical mouse travel in a maze(a simplifiedversion for other scenarios such as a self-driving car, a drone, ...). Suppose you design a reinforcement learning algorithm. Please provide answers to the following questions succinctly as parts of your design: (a)What are thevariablesin your learning algorithm, (b)What data to collect and learn from,(c)What network(s) to use? Can one network be used to learn?(d)What are the inputs and outputs to the network?(e)What is the cost function?(f)How to update the weights?

Write a method public static string getdigits(string phonenumber) that takes an 11-character phone number written with any combination of 11 uppercase letters, lowercase letters and/or digits, and zero or more hyphens, and which returns the digits that a person would have to press on a cell phone to dial that phone number. we will use the mapping of letters to digits given at en.wikipedia.org/wiki/telephone_keypad# /media/file: telephone-keypad2.svg you may assume that the string parameter phonenumber contains some combination of exactly 11 uppercase letters, lowercase letters and/or digits, but that any number of hyphens may be present. you can assume that a hyphen will not appear as the first or last character of the string. do not assum
