Finally, after purchasing a water cooler during the April long challenge, Chef noticed that his water cooler requires 2 liters of water to cool for one hour.

How much water (in liters) would be required by the cooler to cool for N hours?

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

- The first line of input will contain an integer T — the number of test cases. The description of T test cases follows.
- The first and only line of each test case contains an integer N, as described in the problem statement. 

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

For each test case, output the number of liters of water required by the water cooler to cool for N hours. 

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

$1 ≤ T ≤ 1000$
$1 ≤ N ≤ 1000$

----- Sample Input 1 ------ 
2
1
2
----- Sample Output 1 ------ 
2
4

----- explanation 1 ------ 
Test case $1$: As mentioned in the problem statement, $2$ liters of water is required by the water cooler to cool for $1$ hour. 

Test case $2$: $4$ liters of water is required by the water cooler to cool for $2$ hours.
