题目描述

Polycarp doesn't like integers that are divisible by $3$ or end with the digit $3$ in their decimal representation. Integers that meet both conditions are disliked by Polycarp, too. Polycarp starts to write out the positive (greater than $0$ ) integers which he likes: $1, 2, 4, 5, 7, 8, 10, 11, 14, 16, \dots$ . Output the $k$ -th element of this sequence (the elements are numbered from $1$ ).

The first line contains one integer $t$ ( $1 \le t \le 100$ ) — the number of test cases. Then $t$ test cases follow. Each test case consists of one line containing one integer $k$ ( $1 \le k \le 1000$ ).

For each test case, output in a separate line one integer $x$ — the $k$ -th element of the sequence that was written out by Polycarp.
