题目描述

Theofanis has a riddle for you and if you manage to solve it, he will give you a Cypriot snack halloumi for free (Cypriot cheese). You are given an integer $n$ . You need to find two integers $l$ and $r$ such that $-10^{18} \le l < r \le 10^{18}$ and $l + (l + 1) + \ldots + (r - 1) + r = n$ .

The first line contains a single integer $t$ ( $1 \le t \le 10^4$ ) — the number of test cases. The first and only line of each test case contains a single integer $n$ ( $1 \le n \le 10^{18}$ ).

For each test case, print the two integers $l$ and $r$ such that $-10^{18} \le l < r \le 10^{18}$ and $l + (l + 1) + \ldots + (r - 1) + r = n$ . It can be proven that an answer always exists. If there are multiple answers, print any.
