Problem of the Day

You've got an easy one for today. Create a program that iterates over the numbers [1-100] (inclusive). If a number is divisible by 1 print "problem". If a number is divisible by 5 print "of". If a number is divisible by 25 print "the". If a number is divisible by 100 print "day". Thus when you reach 100 your final line of output should be "problemoftheday".

    My very simple C# solution

        static void Main(string[] args)
    {
        for (int i = 1; i <= 100; i++)
        {
            Console.WriteLine(String.Format("problem{0}{1}{2}", (i % 5 == 0 ? "of" : ""), (i % 25 == 0 ? "the" : ""), (i % 100 == 0 ? "day" : "")));
        }
        Console.ReadKey();
    }

    I shall try to make it shorter if I have time later.

    A little shorter

        static void Main(string[] args)
    {
        for (int i = 1; i <= 100; i++)
            Console.WriteLine("problemoftheday".Substring(0, (i % 100 == 0 ? 15 : (i % 25 == 0 ? 12 : (i % 5 == 0 ? 9 : 7)))));
        Console.ReadKey();
    }

    Python

    for i in range(1,101):
    text = "problem"
    if i%5 == 0:
        text += "of"
    if i%25 == 0:
        text += "the"
    if i%100 == 0:
        text += "day"
    print text

    I had broadly the same solution, but for efficiency, I nested the %25 and %100 statements. If i%5 isn't 0, you don't need to test i%25, and if i%25 is 0, you don't need to test i%100.

    #python 2.7
for x in range(100):
    y = x+1
    string = "problem"
    if y%5==0:
        string = string + "of"
        if y%25 == 0:
            string = string + "the"
            if y%100 == 0:
                string = string + "day"
    print string
