Summary

Simple and clean solutions for typical technical interview questions. The solutions are written in Python3.

This repo is a resource for the Technical Interviews Workshops at Northeastern University Seattle campus. Feel free to join the slack channel for this workshop. Note, you must have a husky.neu.edu email address to join the channel:

Prerequisites

You must have the following installed on your machine:

• Python 3.7
• Pytest

How to run the tests

Running the test on the command line

To run a single test file, cd into the tst directory. Then run any test file. For example, to run the test_two_sum.py tests, enter the following command:

$ pytest test_two_sum.py --verbose

To run all tests:

$ pytest

Or if you want to invoke pytest via python, try one of the following:

python -m pytest

python3 -m pytest

You should see the following output:
