You are given an array a of integers with n elements. You are allowed to rearrange the elements of the array in any order. Your task is to determine if it is possible to reorder the array such that for every i from 0 to n-2 (i.e., for all adjacent elements), the absolute difference between consecutive elements is either 5 or 7. That is, for all i such that 0 <= i < n — 1, you need to check if:↵
abs(v[i] — v[i + 1]) = 5 or abs(v[i] — v[i+ 1]) = 7.
abs(v[i] — v[i + 1]) = 5 or abs(v[i] — v[i+ 1]) = 7.
