# Sequence Query

You are given N integer numbers `(A1, A2, A3 … AN)`

. You will also be given some query. Each query will be of the format (L, R). For each query you need to find all the sequence such that`L <= v1 < v2 < v3 … < vk <= R`

, and`(Av1 + Av2 + Av3 + … + Avk)`

is divisible by M. You need to find out the sum of product of all the numbers in all such sequences. Basically `SUM of all possible(Av1 * Av2 * Av3 * … * Avk)`

## Input

The first line contains three integers N, Q, M(1 <= N, Q <= 300000, 1 <= M <= 30). The following line contains N integers A1, A2, A3 … AN(0 <= Ai < 1000000000). The next Q lines each contain two integers. L, R(1 <= L <= R <= N)

## Output

Print Q lines, each line must contain the result of the query modulo 1000000007
