prime number application


You have been tasked with writing an application to remove records (lines) in a flat file where

the number in the first column is strictly less than 7500 and is a prime number. The file is in a

comma separated value (CSV) format that has two fields (columns):

 A number, which is a long unsigned integer and may be non-unique; and

 A string that may contain up to and including 1024 characters.

An example set of inputs and outputs is given in the table below. Note that 7867 is a prime.















The application shall read the file from stdin and write its output to stdout. Examples of

how this application could be used are shown in the table below.

OS Example Usage

Windows type [login to view URL] | python [login to view URL]

Unix cat [login to view URL] | python [login to view URL]

This application will be relied upon by other team members and people outside your team.

The file may contain many records (tens of billions) and thus scalability with respect to run

time and memory usage is important.

Your Solution

We prefer your solution to be written in Python but you may use a different language if you

wish. You are free to use any tools and/or libraries as you see fit. To determine whether a

number is a prime or not, you may: (1) use the sympy Python library, (2) use another library

so long as it easy for us to find – Python packages should be installable via pip or (3) write

your own implementation and provide it as part of your solution.

You should spend less than 1 hour on this exercise.

The deliverable for this exercise is a single source file (.py or equivalent for other languages)

or a Zip file if your solution has multiple source files.

We will be assessing your solution by:

 The correctness of your solution;

 Whether your scalabe is scalable with respect to running time and memory usage;


 Whether it adheres to good programming practices that make this application easy to

use and maintain.
