Solve the programming task below in a Python markdown code block.
A person is said to be sleep deprived if he slept strictly less than 7 hours in a day.

Chef was only able to sleep X hours yesterday. Determine if he is sleep deprived or not.

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

- The first line contains a single integer T — the number of test cases. Then the test cases follow.
- The first and only line of each test case contains one integer X — the number of hours Chef slept.

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

For each test case, output YES if Chef is sleep-deprived. Otherwise, output NO.

You may print each character of YES and NO in uppercase or lowercase (for example, yes, yEs, Yes will be considered identical).

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

$1 ≤ T ≤ 20$
$1 ≤X ≤15$

----- Sample Input 1 ------ 
3
4
7
10

----- Sample Output 1 ------ 
YES
NO
NO

----- explanation 1 ------ 
Test Case 1: Since $4 < 7$, Chef is sleep deprived.

Test Case 2: Since $7 ≥ 7$, Chef is not sleep deprived.

Test Case 3: Since $10 ≥ 7$, Chef is not sleep deprived.
