Dislike of Threes
Description
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.
