Tags skill/problem_solving
Hard Prerequisites
IMPORTANT: Please review these prerequisites, they include important information that will help you with this content.
  • CODING_APTITUDE_ASSESSMENT: Introduction to coding challenges
  • CODING_APTITUDE_ASSESSMENT: IMPORTANT!! Naming your files and functions

    • Make a function that takes two strings as input, and print the common letters that they share.

    The printed letters should:

    • be lowercase
    • be in alphabetical order
    • appear as a single string. Please see the example to see the format of the string
    • There should only be letters in your result, no whitespace, numbers, or special characters

    Example usage:

    • task10("House","computers") should print e, o, s and u exactly. If it prints eosu then that would be incorrect.
    • task10("Hi","there") should print h
    • task10("Foo","bar") should print no common letters

    Check your understanding

    • What should the output look like if there are only 2 common characters? How can you check that your code handles this condition?
    • What should the output look like if there are 3 common characters? How can you check that your code handles this condition?
    • What other special cases are there? How can you check if they work?
