A participant can make 1 submission every 30 seconds. If a contest lasts for X minutes, what is the maximum number of submissions that the participant can make during it?

It is also given that the participant cannot make any submission in the last 5 seconds of the contest.

------ Input Format ------ 

- The first line of input will contain a single integer T, denoting the number of test cases.
- Each test case consists of a single integer X, denoting the number of minutes.

------ Output Format ------ 

For each test case, output the maximum number of submissions a participant can make in X minutes.

------ Constraints ------ 

$1 ≤ T ≤ 30$
$1 ≤ X ≤ 30$

----- Sample Input 1 ------

----- Sample Output 1 ------

----- explanation 1 ------ 
Test case $1$: The contest lasts for $1$ minute, which is $60$ seconds. A participant can make $2$ submissions during this time — for example, in the $5$-th second and in the $48$-th second. Making $3$ or more submissions is impossible.

Test case $2$: The contest lasts for $2$ minutes, which is $120$ seconds. A participant can make $4$ submissions during this time.
