What's the Dot class? It's not included in the starting code, should be String or something

Should have explain better on this seriously, "come before" can be understand as stand before as place in the string, so "2000" start with "2" and "11" start with "1", if sort by string then become "11 2000"

Got it :D It's just that I think many more 6 kyu kata is way harder for solving, maybe due to different in language

This seems to be too easy for 6 kyu, should be 7 kyu?

Also cant find the answer for this crap, to initial is not correct since it will always product rounded number, but the result is a double, to the price getting updated every month then i get 355 after month 6, super confusing

like seriously, cant he just print the expected so that people can see where is the wrong part, sad life

Can someone print the expected in the Array should have same length?, Like this we cant even know what we did wrong

What kind of test passed 207 cases but wrong on 1 eg.(100,100,100,100, I return [(0,20000)]) ??? I think testcases on Swift is wrong

The swift version of this have no test cases at all
