//horrible recursive for loops are not fun
//they aren't a good way to teach something
//why can't we do fizzbuzz?
//or make small games?
//or do data manipulation?
//or solve a problem?
//or something more enjoyable than this?
//maybe CS really should stay a hobbiest, self taught skill
//at least when its a hobby you learn what matters at your own pace
//here its just being given an unrealistic task that, albiet difficult, is not rewarding
//making a diamond like this doesn't teach me good programming
//it teaches me for loops
//and nested for loops are usually not a good way to go about things
//I just want to make command line tools and data parsers for gods sake!
//maybe mom was right, I should just go for law
//sysadmining seems nice though, I could do that
//yeah, law or sysadmin. That seems nice
//or I could write and edit for a living, that doesn't seem too bad
