原题链接：https://zoj.pintia.cn/problem-sets/91827364500/problems/91827370501

BaoBao loves number 7 but hates number 4, so he refers to an integer $x$ as a "lucky integer" if $x$ is divisible by 7 but not divisible by 4. For example, 7, 14 and 21 are lucky integers, but 1, 4 and 28 are not.

Today BaoBao has just found an integer $n$ in his left pocket. As BaoBao dislikes large integers, he decides to find a lucky integer $m$ such that $m \ge n$ and $m$ is as small as possible. Please help BaoBao calculate the value of $m$.

Input

There are multiple test cases. The first line of the input is an integer $T$ (about 100), indicating the number of test cases. For each test case:

The first and only line contains an integer $n$ ($1 \le n \le 100$), indicating the integer in BaoBao's left pocket.

Output

For each test case output one line containing one integer, indicating the value of $m$.

Sample Input

4
1
7
20
28

Sample Output

7
7
21
35
