I would just start toying around with these problems, there's lots of sites out there that aggregate them for you (personally I like https://reddit.com/r/dailyprogrammer https://reddit.com/r/dailyprogrammer). Solving these kinds of problems really are different from your usual day to day on the job coding activities. I'm by no means the best at solving these things, but the more I do it the easier they are going forward. They are useful mostly just for fun or for preparing for interviews where people might do this crap to you. There's actually a yearly code challenge called Advent of Code (https://adventofcode.com/ https://adventofcode.com/) that is starting in December that you can try (though they can be kind of tough). You basically just have to keep doing them and do harder and harder ones and it gets easier, your bag of tricks starts to grow and you realize "Oh, this problem is pretty similar to the problem I did last month, I'll start out with the same approach"
