As a student of the applied mathematics school of UESTC, WCM likes mathematics. Some day he found an interesting theorem that every positive integer's cube can be expressed as the sum of some continuous odd positive integers.
11*11*11 = 1331 = 111+113+115+117+119+121+123+125+127+129+131
Facing such a perfect theorem, WCM felt very agitated. But he didn't know how to prove it. He asked his good friend Tom Riddle for help. Tom Riddle is a student of the computer science school of UESTC and is skillful at programming. He used the computer to prove the theorem's validity easily. Can you also do it?
Given a positive integer N
, you should determine how to express this number as the sum of N
continuous odd positive integers. You only need to output the smallest and the largest number among the N integers.
The input contains an integer on the first line, which indicates the number of test cases. Each test case contains one positive integer N
on a single line(0 < N
For each test case, output two integers on a line, the smallest and the largest number among the N
continuous odd positive integers whose sum is N
