Pretty myopic viewpoint. You wasted an afternoon figuring out graph-traversal & loop detection from first principles -- using and stretching your mental abilities -- rather than being spoonfed it? That's absurd. Utterly absurd.

I get no satisfaction from rediscovering CS concepts & algorithms first put to paper by the field's pioneers between 1940-1970s, though it sounds like you do.

Some wood (or metal) workers take pride in making their own tools, and others, who are like me, buy off the shelf tools and use them to make actual things that people buy.

I'm insulted, but I won't drag this out.
