1. Given a stair of N steps, and an array k of step sizes, write an algorithm/ function to compute the number of possible ways to climb it. (30 min) 2. Given 100 Questions with their choices as an array of JSON. Design a system that queries 10 questions at a time and records their answers. And when the user requests again for question, a new set of 10 questions and choices is sent. write a server for it. (30 min) I answered both questions with a little bit of help on the second one, but didnot get an offer. Neither did I get a feedback on what went wrong and what were they expecting. HR doesnot reply mails, nor answer calls.
