Polar bears like unique arrays — that is, arrays without repeated elements.

 You have got a unique array *s* with length *n* containing non-negative integers. Since you are good friends with Alice and Bob, you decide to split the array in two. Precisely, you need to construct two arrays *a* and *b* that are also of length *n*, with the following conditions for all *i* (1 ≤ *i* ≤ *n*):
 -  *a*<sub class="lower-index">*i*</sub>, *b*<sub class="lower-index">*i*</sub> are non-negative integers; -  *s*<sub class="lower-index">*i*</sub> = *a*<sub class="lower-index">*i*</sub> + *b*<sub class="lower-index">*i*</sub> . 
Ideally, *a* and *b* should also be unique arrays. However, life in the Arctic is hard and this is not always possible. Fortunately, Alice and Bob are still happy if their arrays are almost unique. We define an array of length *n* to be almost unique, if and only if it can be turned into a unique array by removing no more than <img align="middle" class="tex-formula" src="https://espresso.codeforces.com/2265c348fd0c0c2877464189b0017364c212a242.png" style="max-width: 100.0%;max-height: 100.0%;"/> entries.

For example, the array [1, 2, 1, 3, 2] is almost unique because after removing the first two entries, it becomes [1, 3, 2]. The array [1, 2, 1, 3, 1, 2] is not almost unique because we need to remove at least 3 entries to turn it into a unique array.

So, your task is to split the given unique array *s* into two almost unique arrays *a* and *b*.
The first line of the input contains integer *n* (1 ≤ *n* ≤ 10<sup class="upper-index">5</sup>).

The second line contains *n* distinct integers *s*<sub class="lower-index">1</sub>, *s*<sub class="lower-index">2</sub>, ... *s*<sub class="lower-index">*n*</sub> (0 ≤ *s*<sub class="lower-index">*i*</sub> ≤ 10<sup class="upper-index">9</sup>).
