Chef has an integer N. It is known that the largest [odd] [divisor] of N does not exceed 10^{5}.
Determine two non-negative integers A and B such that A^{2} + B^{2} = N, or report that no such pair exists.
------ Input Format ------
- The first line of input will contain a single integer T, denoting the number of test cases.
- Each test case consists of a single integer N.
------ Output Format ------
For each test case, output space-separated A and B such that A^{2} + B^{2} = N or -1 if no such pair exists.
------ Constraints ------
$1 ≤ T ≤ 10^{5}$
$1 ≤ N ≤ 10^{15}$
- Largest odd divisor of $N$ won't exceed $10^{5}$.

Test case $1$: A possible pair $(A, B)$ such that $A^{2} + B^{2} = N$ is $(8, 6)$. Here, $8^{2} + 6^{2} = 64+36 = 100$.
Test case $2$: There is no pair $(A, B)$ such that $A^{2} + B^{2} = N$.
Test case $3$: A possible pair $(A, B)$ such that $A^{2} + B^{2} = N$ is $(2, 3)$. Here, $2^{2} + 3^{2} = 4+9 = 13$
Test case $4$: A possible pair $(A, B)$ such that $A^{2} + B^{2} = N$ is $(0, 2)$. Here, $0^{2} + 2^{2} = 0+4 = 4$.
