This turned out to be interesting puzzle. Seemingly so simple thing made me think a lot.
Problem statement:
You’re given a string, which is a connection string to MongoDB. It consists of parts. The parts are delimited by various characters:
- between username and password, there is ‘:’
- after password comes ‘@’
- after the ‘@’ comes host name
We want to mask any password characters with ‘*’ character.
Write an algorithm (function) that takes in a string, and writes out a masked string.

Me: a code enthusiasta, technology optimist, but also a realist. In my blog something like 80% of the articles are technology related - mostly in English and Finnish. I like to envision and ponder about things, how life could be, what we are doing wrong today, and so on. "Invented" a facebook -like system in 2000, as a short product pamphlet. Haven't yet realized the 20+ ideas that might have become big things. Maybe learning this skill one of these days!
