Students in Computer Science would like to understand the concept of Ohm’s law. You are required to write an application that will allow them to calculate the relation between Voltage, Current and Resistance using the formulas below.
Scenario:
Your friend is developing a maze puzzle game and already designed a module which can generate a random maze. The maze has one entry and one exit point. Now he needs to develop the module which will find the path from entry to exit points for randomly generated maze. Your friend wants the path searching should be quickest. He can use only Stack or Queue data structures to store maze’s visited locations for path generation. He is unable to decide the selection of data structure and asked you to help him.
Question:
From Stack and Queue data structures which data structure you will suggest using for entry to exit path finding module? Select a data structure and give comments in favour to justify your selection. Also mention why you are not selecting the other data structure?
