Given a positive integer (n). Find the smallest integer whose decimal representation has length (n) and consists only of (3)s and (6)s such that it is divisible by both (33) and (66). If no such integer exists, print (-1). The first line contains a single integer (t) ((1\le t\le 500)) — the number of test cases. The only line of each test case contains a single integer (n) ((1\le n\le 500)) — the length of the decimal representation. For each test case, output the smallest required integer if such an integer exists and (-1) otherwise. For (n=1), no such integer exists as neither (3) nor (6) is divisible by (33). For (n=2), (66) consists only of (6)s and it is divisible by both (33) and (66). For (n=3), no such integer exists. Only (363) is divisible by (33), but it is not divisible by (66). For (n=4), (3366) and (6666) are divisible by both (33) and (66), and (3366) is the smallest.
