Take in an Int array and move all the zeroes to the end in place. It doesn’t matter how the non-zero numbers are ordered. Preferably as efficient and as space efficient as possible. Example: Input : [ 3, 0, 2, 0, 0, 4, 1, 0 ] Accepted Output: [ 4, 2, 3, 1, 0, 0, 0, 0 ]

I was asked two questions. Q 1. You are given two version numbers of a software, like Version 10.3.4 and Version 10.3.41. Write a program to find out which of the version numbers are the latest. If version 1 is latest output -1, if version number 2 is latest output +1 else output 0 if same version. Both the version numbers are taken as string. He also asks to make the program of minimum time complexity as we can. At the end he also asked the difference between an iterative program and one with recurrence and their advantages and disadvantages. Q 2. Given two files with a list of application IDs (or some kind of data) stored in them , write a program to compare the data in the two files and output all the common data found in each. What data structure would you use and why ? Give a minimum time and space complexity algorithm. Why did you choose the particular data Structure or algorithm ?
