+/* Explanation:
+Input:
+
+t: Number of test cases.
+For each test case, n: Number of elements in the array and a[]: The array.
+Approach:
+
+The goal is to form a permutation of the array such that the greatest GCDs are computed in order.
+Sort the array, start with the largest number, and iteratively pick the number that gives the maximum GCD with the current GCD.
+Algorithm:
+
+Start with the largest number in the array as the first element in the permutation.
+Use a greedy approach to maximize the GCD at each step.
+Track visited elements to avoid repetition.
+Output:
+
+Print the reordered array for each test case.
+This approach ensures an optimal solution using sorting and iterative GCD calculations. The complexity is manageable due to efficient GCD computation.
