This is a very simple problem! Your only job is to calculate $a + b + c + d$!

There are several cases.
In the first line, there is a single integer $T(T ≤ 200)$.
In the next $T$ lines, each line contains four integers $a, b, c$ and $d(-2^{61} ≤ a,b,c,d ≤2^{61})$.

output $T$ lines.
Each line output one integer represent the answer of $a + b + c + d$.
