**Mr. X** has given a lab task to his students. He has provided them with a pseudo code of a function. Their task is to implement a similar function that will give same output as the following function. Func(n) { ret = 0 for( i = 1; i < n; i++) { if( gcd(i,n) > 1) { ret = ret + i } } return ret } Input: ------ Input starts with an integer **T (1 ≤ T ≤ 1500)**, denoting the number of test cases. Each of the next **T** lines contain an integer **n (1 ≤ n ≤ 1,000,000,000)**. Output: ------- For each integer **n**, print the value of **Func(n)** in a line. Follow the output format of the sample. Sample Input ------------ 3 4 6 9 Sample Output ------------- 2 9 9
