🛠 Capstone Project

Sum of multiples of 3 or 5 below 20

Add up every number below 20 that is a multiple of 3 or 5, and print the total. (The numbers are 3, 5, 6, 9, 10, 12, 15, 18 — and the answer is 78.)

Requirements

  • Loop over the numbers from 1 up to (but not including) 20
  • Select multiples of 3 OR 5 using % and ||
  • Accumulate them into a mutable sum
  • Print the final total with println!

When you submit, the Academy AI evaluates your code on accuracy (50%), code cleanliness (25%) and performance (25%). Score 70%+ to earn your certificate.
