algorithms's Introduction

Algorithms

A series of programming problems written and solved in Python.

Instructions

Download this folder as a .zip and start solving problems. The questions are all setup already. They specify an example, ideal time efficiency, difficulty and include test cases that you can uncomment out and run to ensure your function works.

To run a .py file from terminal run:

$> python arrays.py

Please let me know if you find any issues or would like the methods better to be commented.

Topics Covered

Problems cover the following topics:

  • Arrays
  • Dynamic Programming
  • Graphs
  • Bit Manipulation
  • Data Structures
    • Stacks
    • Queues
    • Heaps

Sources

Problems come from a variety of sources including:

  • Codility.com
  • HackerRank.com
  • Careercup.com
  • ProjectEuler.net
  • Reddit.com/r/cscareerquestions
  • Cracking the Coding Interview (Gayle Laakmann)

algorithms's Issues

Bit Manipulation questions incorrectly answered!

The solutions given to the Bit Manipulation questions are incorrectly answered.
I'd assume they mean to actually move around bits, as in a logical shifting of bits left/right to multiply/divide (for example).
However, the answers have been created by just casting numbers from binary to int, or converting to string and manipulating the characters. They don't actually involve bitwise manipulation!
