Loop Challenge

In this lab you will solve three classic programming problems using loops. Each answer should be printed to stdout.

Task 1: FizzBuzz

Print numbers from 1 to 30. But:

• If a number is divisible by 3, print Fizz instead
• If a number is divisible by 5, print Buzz instead
• If divisible by both 3 and 5, print FizzBuzz
• Otherwise print the number

Task 2: Sum of Even Numbers

Calculate and print the sum of all even numbers from 1 to 100 (inclusive). Print the result as: Sum of evens: 2550

Task 3: Find Primes up to N

Find all prime numbers up to 50. A prime number is a number greater than 1 that is only divisible by 1 and itself. Print them on one line separated by spaces.

Hints

• For FizzBuzz: check divisibility by 15 (3×5) first, then 3, then 5
• For even sum: use range(2, 101, 2) or check n % 2 == 0
• For primes: for each candidate n, check if any number from 2 to n-1 divides it evenly
