Meta Interview Question
Technical Phone Screen Coding question: You will be supplied with two data files in CSV format . The first file contains statistics about various dinosaurs. The second file contains additional data. Given the following formula, speed = ((STRIDE_LENGTH / LEG_LENGTH) - 1) * SQRT(LEG_LENGTH * g) Where g = 9.8 m/s^2 (gravitational constant) Write a program to read in the data files from disk, it must then print the names of only the bipedal dinosaurs from fastest to slowest.

Create a class Dinosour - class variables are name, and speed Create a map by parsing file 2 and adding key as Dinosour name and value as stride length. Only add Dinosour where stance(string split[2] == bipedal) Create a List , populate the list by parsing file1 , split using string split and only process Dinosours which are present in map. Calculate the speed using formula and create a new Dinosour object (name and speed). Create a comparator mycmp .( do comparison based on speed of Dinosour object, if speed is same then compare based on name). Sort the list based on the comparator. Print the list.
