So far this week we’ve had a pair of related posts at the DailyProgrammer subreddit1:
Basically, if you’re given a string with vowels, take them out. If you’re given one without vowels, put them back in. One of the two is certainly easier than the other2. :)
While I’ve been getting a fair few programming exercises from Reddit’s /r/dailyprogrammer, more recently I’ve started following a few other sub-Reddits, such as /r/programming and /r/netsec. While browsing the former, I came across this intriguing gem of a problem: HashChallenge: can you find the lowest value SHA-512 hash?
Today’s intermediate challenge on Reddit’s /r/dailyprogrammer intrigued me somewhat, so I decided to take a crack at it. The basic idea is if you are given a number, try converting it to all bases from 2 to 64 (with a special encoding). Print out any of those that are words.
For example, if you interpret the number 44,269 as a base 16 (Hexadecimal) number, you get the word “aced”. So just how many of these words are there out there?
