ADDGP - Enjoy Adding GP to Series
You are initially given an empty array of Size N (<=100000). (i.e. each element is 0).
Given 2 <= R <=109.
Now you are given 3 types of query:
- "0 St i1 i2": means add (St, St*R, St*R^2, ...) GP from i1 to i2 respectively. (Means add the GP with start term St and common ratio R in the series beginning from i1 and ending at i2.)
- "1 i j": means find the sum of values of the array from index i to index j with modulo 1000000007.
- "2 i": resets the i-th index array to 0.
Constraints
Queries <=90000
1 <= St <= 109
Input
First Line contains N R Q.
Then Follows Q lines, each line can be of any 3 types described above.
Output
Output only second type of Query.
Example
Input:
2 2 3
0 2 1 2
1 1 2
1 2 2
Output:
