Row GCD
You are given two positive integer sequences $$$a_1, \ldots, a_n$$$ and $$$b_1, \ldots, b_m$$$. For each $$$j = 1, \ldots, m$$$ find the greatest common divisor of $$$a_1 + b_j, \ldots, a_n + b_j$$$.
The first line contains two integers $$$n$$$ and $$$m$$$ ($$$1 \leq n, m \leq 2 \cdot 10^5$$$).The second line contains $$$n$$$ integers $$$a_1, \ldots, a_n$$$ ($$$1 \leq a_i \leq 10^{18})$$$.The third line contains $$$m$$$ integers $$$b_1, \ldots, b_m$$$ ($$$1 \leq b_j \leq 10^{18})$$$.
Print $$$m$$$ integers. The $$$j$$$-th of them should be equal to GCD$$$(a_1 + b_j, \ldots, a_n + b_j)$$$.
