That's just sad

It blows my mind that anyone hired to write code full time would struggle with this. It took me two minutes to write the FizzBuzz quick from that page, and about 85% of that time was typing :)

public class FizzBuzz
{
     public static void main(String[] args)
     {
          for (int index = 1; index <= 100; index++)
          {
               if (index % 3 == 0 && index % 5 != 0)
                    System.out.println("Fizz");
               else if (index % 5 == 0 && index % 3 != 0)
                    System.out.println("Buzz");
               else if (index % 3 == 0 && index % 5 == 0)
                    System.out.println("FizzBuzz");
          }
     }
}

And this just scares the hell out of me because I know how true it is:

If you can successfully write a loop that goes from 1 to 10 in every language on your resume, can do simple arithmetic without a calculator, and can use recursion to solve a real problem, you're already ahead of the pack!

Now, the only language I know "like the back of my hand" is Java because I use it everyday, but I am comfortable with C, C#, PHP and Python. I can not only write loops in all five, but write at least fairly useful code in them. Despite having a math learning problem, I can do basic arithmetic without a calculator and can use recursion when I need to. For example, it never occurred to me in college that many of my peers would struggle with this:

public void getFullListing(File startPath, ArrayList list)
{
     list.add(startPath);
     File[] contents = startPath.listFiles();
     for (File file : contents)
     {
          if (file.isDirectory())
               getFullListing(file, list);
          else
               list.add(file);
     }
}

In 12 lines of code, I just listed the contents of an entire folder in rough order (listFiles() doesn't return an ordered array). I've seen code like this, turned into two-two and a half page monstrosities:

#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>

int main()
{
     FILE *alphas = fopen("alphas.txt", "w");
     FILE *digits = fopen("digits.txt", "w");
     FILE *miscel = fopen("miscel.txt", "w");
     FILE *inputf = fopen("inputf.txt", "r");
     
     while ( !feof(inputf) )
     {
          int c = (char)fgetc(inputf);
          if (isalpha(c)) fputc(c, alphas);
          if (isdigit(c)) fputc(c, digits);
          if (!isalpha(c) && !isalpha(c)) fputc(c, miscel);
     }
     
     fclose(alphas);
     fclose(digits);
     fclose(miscel);
     fclose(inputf);

     return 0;
}
