Daily Coding Challenge

This repository documents my journey through the daily coding challenges on freeCodeCamp.org. It includes both the problem statements and my personal solutions, primarily written in Python. The goal is to consistently practice problem-solving and learn something new every day.

Code structure

Below is the template for a python file (with simple test method):

from module_test import do_test

# Function/method
def method_name(param_1: list, param_2: int) -> bool:
	# TODO: Solve somethings...

	# Return the result
	return True

# Do test
do_test(function_name="method_name", should_return=True, param_1=[1, 2, 3], param_2=0)
do_test(function_name="method_name", should_return=False, param_1=[0, 2, 4], param_2=1)
do_test(function_name="method_name", should_return=True, param_1=[], param_2=8)
