	Question 1 -- sumOfTwo(a,b,v): You have two integer arrays, a and b, and an integer target value v. Determine whether there is a pair of numbers, where one number is taken from a and the other from b, that can be added together to get a sum of v. Return true if such a pair exists, otherwise return false.

	Question 2 -- stringReformatting(string): The string s contains dashes that split it into groups of characters. You are given an integer k that represents the number of characters in groups that your output should have. Your goal is to return a new string that breaks s into groups with a length of k by placing dashes at the correct intervals. If necessary, the first group of characters can be shorter than k. It is guaranteed that there are no consecutive dashes in s.

	For s = "2-4a0r7-4k" and k = 4, the output should be stringReformatting(s, k) = "24a0-r74k";

	The input string "2-4a0r7-4k" is split into three groups with lengths of 1, 5 and 2. Since k = 4, you need to split the string into two groups of
