Exacly, it's very nice =))

It didn't work for me; problem is, the test cases have different result than what the actual formula gives. Am i doing something wrong?

Yep ma bad. sry

• Well, Thanks Oleksandr for posting your Comment
• The Given range determine Only the input Year Passed to the function and Since the passed Year in the case above is 8999 <= 9000 so it's Consistent with the range But, the Output year Could exceed this range that's Why you've felt confused, Hope this makes it clearer Now, Oleksandr
• Hope you've Enjoyed Form the minimum, Row Weights , as well
• Wish you all the Best On/Off CW .. Regards .. Zizou

Please correct details or tests in java lang. Input Year with in range (1000 ≤ y ≤ 9000); test: assertEquals(9012, HappyYear.nextHappyYear(8999));

Thanks! It worked!

For those who stuck on this in java with precision issues u may use BigDecimal with MathContext.DECIMAL128

i dont get it too...

Yep. Worse kata that i've seen.

it's a nuke!
