Given two unique integer arrays $a and $b, and an integer target value $v, create a function to determine whether there is a pair of numbers that add up to the target value $v, where one number comes from one array $a and the other comes from the second array $b.
Return true if there is a pair that adds up to the target value and false otherwise.
