B'In a desperate attempt to obtain your waifu favorite character, you have hacked into the source code of the game. After days of struggling, you finally find the binary string that encodes the gacha system of the game. In order to decode it, you must first solve the following problem. You are given a binary string s of length n . For each pair of integers (l, r) (1 <= q l <= q r <= q n) , count the number of pairs (x, y) (l <= q x <= q y <= q r) such that the amount of mathtt{0} equals the amount of mathtt{1} in the substring s_xs_{x+1}...s_y . Output the sum of counts over all possible (l, r) modulo 10^9+7 . The first line contains t ( 1 <= q t <= q 1000 ) -- the number of test cases. Each test case contains a binary string s ( 1 <= q |s| <= q 2 cdot 10^5 ). It is guaranteed s only contains characters mathtt{0} and mathtt{1} . It is guaranteed the sum of |s| over all test cases does not exceed 2 cdot 10^5 . For each test case, output an integer, the answer modulo 10^9+7 . '...
