题目描述
You have N integers A1, A2, ... , AN. You are asked to write a program to receive and execute two kinds of instructions:
1. C a b means performing Ai = (Ai2 mod 2018) for all Ai such that a ≤ i ≤ b.
2. Q a b means query the sum of Aa, Aa+1, ..., Ab. Note that the sum is not taken modulo 2018.
输入描述:
The first line of the input is T(1≤ T ≤ 20), which stands for the number of test cases you need to solve.
The first line of each test case contains N (1 ≤ N ≤ 50000).The second line contains N numbers, the initial values of A1, A2, ..., An. 0 ≤ Ai < 2018. The third line contains the number of operations Q (0 ≤ Q ≤ 50000). The following Q lines represents an operation having the format "C a b" or "Q a b", which has been described above. 1 ≤ a ≤ b ≤ N.
输出描述:
For each test case, print a line "Case #t:" (without quotes, t means the index of the test case) at the beginning.
You need to answer all Q commands in order. One answer in a line.
