You are given several queries. In the $*i*$-th query you are given a single positive integer $*n*_{*i*}$. You are to represent $*n*_{*i*}$ as a sum of maximum possible number of composite summands and print this maximum number, or print -1, if there are no such splittings.
An integer greater than $1$ is composite, if it is not prime, i.e. if it has positive divisors not equal to $1$ and the integer itself.
Input
The first line contains single integer $*q*$ ($1 ≤ *q* ≤ 10^{5}$) — the number of queries.
$*q*$ lines follow. The ($*i* + 1$)-th line contains single integer $*n*_{*i*}$ ($1 ≤ *n*_{*i*} ≤ 10^{9}$) — the $*i*$-th query.
Output
For each query print the maximum possible number of summands in a valid splitting to composite summands, or -1, if there are no such splittings.
Note
$12 = 4 + 4 + 4 = 4 + 8 = 6 + 6 = 12$, but the first splitting has the maximum possible number of summands.
$8 = 4 + 4$, $6$ can't be split into several composite summands.
$1, 2, 3$ are less than any composite number, so they do not have valid splittings.
