## Descriptions

Let’s denote correct match equation (we will denote it as CME) an equation a+b=c there all integers a, b and c are greater than zero.
For example, equations 2+2=4 (||+||=||||) and 1+2=3 (|+||=|||) are CME but equations 1+2=4 (|+||=||||), 2+2=3 (||+||=|||), and 0+1=1 (+|=|) are not.

Now, you have n matches. You want to assemble a CME using all your matches. Unfortunately, it is possible that you can’t assemble the CME using all matches. But you can buy some extra matches and then assemble CME!
For example, if n=2, you can buy two matches and assemble |+|=||, and if n=5 you can buy one match and assemble ||+|=|||. Calculate the minimum number of matches which you have to buy for assembling CME.
Note, that you have to answer q independent queries.

## Input

The first line contains one integer q (1≤q≤100) — the number of queries.
The only line of each query contains one integer n (2≤n≤109) — the number of matches.

## Output

For each test case print one integer in single line — the minimum number of matches which you have to buy for assembling CME.
