( 25096 ) A Consecutive Sum Riddle PROGRAMMING math 800

B'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} <= l < r <= 10^{18} and l + (l + 1) + ldots + (r - 1) + r = n . The first line contains a single integer t ( 1 <= t <= 10^4 ) -- the number of test cases. The first and only line of each test case contains a single integer n ( 1 <= n <= 10^{18} ). For each test case, print the two integers l and r such that -10^{18} <= l < r <= 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. In the first test case, 0 + 1 = 1 . In the second test case, (-1) + 0 + 1 + 2 = 2 . In the fourth test case, 1 + 2 + 3 = 6 . In the fifth test case, 18 + 19 + 20 + 21 + 22 = 100 . In the sixth test case, (-2) + (-1) + 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 = 25 . '...
