Ok, so I was stamping out a recent (quite simple) assignment for a class. The assignment required the separation of each place value in an integer. Since the information came into the program as a string, I stamped out a simple solution using some easy loops and handy methods available in the String class (of the .Net 2.0 class libraries). However, a quick skim over the rubric included 5% for correctly using div and mod to parse out the integer values. I immediately flipped back into my program, then froze for a second..
then another…
then 2 more…
I was completely blanking. I know its a simple task, its just I have become so accustomed to the incredible abundance and availability of a dozen methods for every little task that I blanked for a good minute, just stonewalled. I knew I had written this code before, everyone has done it at least once in some ‘Intro to Programming Theory’ class, and the concept was easy enough, but it just wouldn’t come. Cursing the professor for such a trivial demand, I went and got a cup of coffee.
Upon returning I realized how stupid and petty I was being. While I do often rely on cool class libraries and the methods they provide, I really just have to stop being so self-righteous and realize how likely it was that much of the class would be completely stuck on such a task. We spend so much time today learning about existing technologies and API’s that we forget the core of programming: Problem Solving.
I quickly slapped together the following C# method:
static int[] toIntArray(string input)
{
int i = 0;
int digit;
List<int> ints = new List<int>();
for (int numdigits = input.Length; numdigits > 0; numdigits–)
{digit = Convert.ToInt32(input) / (int)Math.Pow(10.0, (double)(numdigits - 1));
digit = digit % 10;
ints.Add(digit);
i++;
}
return ints.ToArray();
}
In retrospect, its quite simple, I just hope that this was my ‘moment of realization’ and I don’t get so inundated again as to the point where I can’t do the simple stuff on my own anymore.

) but I’ve determined that we need a deeper dimension of weight on relationship weighting (when scoring). While one possibility is to just add another variable to our existing weight-determination system, I am leaning towards something more broad. What if the programmer only had to specify a relationship, and through a combination of its occurrence, how closely it paralleled term-based similarity, and how often that relationship type was used to rank a selected result (would require gui integration, but for this proof of concept thats ok in my head) to build an individualized weight for each relationship.
