Project Euler: JS Solution Explained!
Part 1 of 18
In this series, I will be discussing Project Euler Solutions. 'Project Euler' helps in improving problem-solving and programming skills. Remember, there is always a better solution to the problem. 💯
Project Euler: #1 - Multiples of 3 or 5
Problem If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. Problem Description This is a more straightforward prob...

Project Euler: #17 - Number letter counts
Problem If the numbers 1 to 5 are written out in words: one, two, three, four, five, then there are 3 + 3 + 5 + 4 + 4 = 19 letters used in total. If all the numbers from 1 to 1000 (one thousand) inclusive were written out in words, how many letters w...

Project Euler: #14 - Longest Collatz sequence
Problem The following iterative sequence is defined for the set of positive integers: n → n/2 (n is even) n → 3n + 1 (n is odd) Using the rule above and starting with 13, we generate the following sequence: 13 → 40 → 20 → 10 → 5 → 16 → 8 → 4 → 2 → ...
