Activity: Printing Prime Numbers from 1 to 100

Scenario

You're working on a project that calculates different mathematical formulae. You start with a basic one that prints prime numbers.

Aim

Write a view that prints the prime numbers from 1 to 100 to the browser.

@functions
{
  public bool IsPrime(int n)
  {
    if (n <= 1) return false;
    if (n <= 3) return true;
    if (n % 2 == 0 || n % 3 == 0) return false;
    for (var i = 5; i * i <= n; i = i + 6)
      if (n % i == 0 || n % (i + 2) == 0)
      return false;
    return true;
  }
