I think that n%3 mean that a number divide by 3 and what you want is the remainder. n//3%3 mean that you are diving the number dirst and rounding it down, then you are doinging another division and looking for it's remainder. Same with n//9%3 This just mean that you are dividing by 9 first and rounding down, then you divide by 3 and get the remainder.
For example;
5%3 would have a remainder of 2.
5//3%3 would be 1.66 and round down would have 1, then you find the remainder which is 1.
12//9%3 would be 1.33 and round down you get 1, then you find the remainder of 1/3 which is 1.

I mean how you are calculating the exact hands by dividing. I could think of three nested(one for each person ) for loops that gives me array of numbers, but I was failing to stop the 3 nested at exact hands given as input

In the table given in the kata description, observe that P1, P2, P3 are simply counting in ternary. So this kata is an exercise in converting a decimal integer to ternary.

Can you please explain this solution

.

Not a kata issue, and those are several input values together, please read this: https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution

im having issues with hidden test case in java. Anyone getting same? test case is below. It says my code returns 0 running the kata here, but i run my code in my IDE and its returning -1 which the Kata expects.

what do you mean chrono79, i didnt understand. you also shared answer. I posted to check if my understanding is correct or not.
