How Should Schools Grade Unexpected-But-Correct Answers On Coding Tests? - Slashdot[^]

I solved this back in the early 80's using Turbo Pascal. Back then, the solution wasn't "unexpected", because we didn't have convenient framework methods available to us that actually did the math. Here's my approach, converted to C# from that ancient Pascal code (yes, I still have source code from the 80's on my box).

static int CountLeapYears2(int minYear, int maxYear)
{
    // do the basic math up here so we don't clutter the final expression
    int years   = (maxYear - minYear);

    // A leap year is evenly divisible by 4, and those that are divisible by 100 AND 400. 
    // This is why I use 0.03 to find the number of periods to subtract from the number 
    // of years being evaluated.
    int periods = (int)(years * 0.03);

    int count   = (int)((years - (years * 0.03)) * 0.25);
    return count;
}


It should be noted that iterating from the minimum DateTime value to the maximum DateTime value with the C# DateTime.IsLeapYear() takes a measurable amount of time (for me, it was 0.0068359 seconds), while my almost 40-year old method did not produce a measurable duration at all. In the ineterst of completeness, here's my iterative method:

static int CountLeapYears1(int minYear, int maxYear)
{
    int count = 0;
    for (int i = minYear; i <= maxYear; i++)
    {
        if (DateTime.IsLeapYear(i))
        {
            count++;
        }
    }
    return count;
}
