If there are several such sequences, any of them is acceptable. It can be proven that at least one valid sequence always exists for any integern>1n > 1n>1. You have to answertttindependent test cases. The first line of the input contains one integerttt(1≤t≤50001 \le t \le 50001...

Everyone knows what the Fibonacci sequence is. This sequence can be defined by the recurrence relation: F1 = 1, F2 = 2, Fi = Fi - 1 + Fi - 2(i > 2). We'll define a new number sequenceAi(k)by the formula: ...

To solve it we should look on how sequence behaves modulo . We may see that it actually can be split into several arithmetic progressions with step : we increase current number until it's not less than , that is . At this point we subtract from this number and obtain number . Since th...
