B'You are given an integer n . The function C(i,k) represents the number of distinct ways you can select k distinct numbers from the set { 1, 2, ldots, i } and arrange them in a circle ^ dagger . Find the value of sum limits_{i=1}^n sum limits_{j=1}^i <= ft( C(i,j) bmod j right). Here, the operation x bmod y denotes the remainder from dividing x by y . Since this value can be very large, find it modulo 10^9+7 . ^ dagger In a circular arrangement, sequences are considered identical if one can be rotated to match the other. For instance, [1, 2, 3] and [2, 3, 1] are equivalent in a circle. The first line contains a single integer t ( 1 <= q t <= q 10^5 ) -- the number of test cases. The only line of each test case contains a single integer n ( 1 <= n <= 10^6 ). For each test case, output a single integer on a new line -- the value of the expression to be calculated modulo 10^9+7 . In the first test case, C(1,1) bmod 1 = 0 . In the second test case: '... |
