How to get rid of `deprecated conversion from string constant to ‘char*’` warnings in GCC?
...
THIS IS HORRIBLY BAD PRACTICE, and I'm sad it got all those votes. Warnings are not there so that you ignore them. Warnings are there telling you "dude, you're doing something that could be wrong, be careful", and you should only suppress them when you wanna respond like "sh...

Why does this method print 4?

When we first get into main, the space left over is X-M. Each recursive call takes up R more memory. So for 1 recursive call (1 more than original), the memory use is M + R. Suppose that StackOverflowError is thrown after C successful recursive calls, that is, M + C * R <= X and M + C * (R + 1)...
