A string is binary, if it consists only of characters "0" and "1".String v is a substring of string w if it has a non-zero length and can be read starting from some position in string w. For example, string "010" has six substrings: "0", "1", "0", "01", "10", "010". Two substrings are considered different if their posi...

The first line contains an integer n (1 ≤ n ≤ 105). The next line contains n integers a1, a2, ..., an (0 ≤ ai ≤ 1012) — Mr. Bitkoch's sausage. Please, do not use the %lld specifier to read or write 64-bit integers in С++. It is preferred to use the cin, cout streams or the %I64d specifier.

The first line contains a single integer $$$T$$$ ($$$1 \le T \le 1000$$$) — the number of queries. Each of the next $$$T$$$ lines contains two integers $$$l$$$ and $$$r$$$ ($$$1 \le l \le r \le 998244353$$$) — inclusive borders of the range. It is guaranteed that testset only includes queries, which have at least one s...

Print $$$T$$$ lines, each line should contain the answer — two integers $$$x$$$ and $$$y$$$ such that $$$l \le x, y \le r$$$, $$$x \ne y$$$ and $$$x$$$ divides $$$y$$$. The answer in the $$$i$$$-th line should correspond to the $$$i$$$-th query from the input. If there are multiple answers, print any of them.
