CODEFORCES 1181A

CODEFORCES 1181A - Chunga Changa Link to Ques -  CodeForces 1181A Approach It's easy to calculate how much coconuts we will buy:  k = ⌊ x + y z ⌋ k = ⌊ x + y z ⌋  (suppose that all money transferred to a single person, this way the number of bought coconuts would be clearly maximal) If  k = ⌊ x z ⌋ + ⌊ y z ⌋ k = ⌊ x z ⌋ + ⌊ y z ⌋ , then the answer is  ⟨ k , 0 ⟩ ⟨ k , 0 ⟩ . The remaining case is a bit harder. Let's notice, that there is no need to transfer  ≥ z ≥ z  chizhiks, since the one transferring money could have used  z z  chizhiks to buy one more coconut herself. Also it's optimal to transfer coins such that the remainder modulo  z z  of the receiving part will turn to be exactly zero (we could have simply transfer less for the same effect). So the answer is  ⟨ k , min ( z − ( x mod z ) , z − ( y mod z ) ) ⟩ ⟨ k , min ( z − ( x mod z ) , z − ( y mod z ) ) ⟩ . 1 2 3 4 5 6 7 8 9 10 1...
