HackerRank

HackerRank is a platform where developers can hone their problem-solving skills in various domains such as Algorithms, Mathematics, Data Structures, AI, and more.

Developers can

• participate in coding contests,
• practice challenges,
• prepare for coding interview,
• get certifications and
• connect with tech recruiters.

This repository contains my personal solution on HackerRank Challenges:

CHALLENGES:

1. Python

Ref: https://www.hackerrank.com/domains/python

• Introduction (operators, loops, if-else, function)
• Basic Data Types (list, tuple, dictionary, list comprehension)
• Strings (split, join, format, alignment, validators)
• Sets (add, remove, union, intersection)
• Math (round, divmod, math library, cmath library)
• itertools (permutation, combination, groupby, product)
• Collections (counter, deque, namedtuple)
• Date and Time (time delta, calendar module)
• Errors and Exceptions (exceptions - try, except)
• Classes (built-in methods - double_underscore, overloading)
• Built-ins (zipped, sort, eval, any, all)
• Python Functionals (map, lambda, reduce, filter)
• Regex and Parsing (re, match, findall, sub, HTMLParser)
• XML (ElementTree, etree, fromstring, getroot)
• Closures and Decorators (inner-func, @wrapper)
• Numpy
