Description
You are given Circular ArrayA0 ,?A1 ,?...,?AN? -? 1. There are two types of operations with it:
- INC(Lf,?RG,?V)-This operation increases each element on the segment [Lf,?RG] (Inclusively)V;
- Rmq(Lf,?RG)-This operation returns minimal value on the segment [Lf,?RG] (Inclusively ).
Assume segments to be circular, so ifN? =? 5 andLf? =? 3 ,?RG? =? 1, it means the index sequence: 3 ,? 4 ,? 0 ,? 1.
Write Program to process given sequence of operations.
Input
The first line contains integerN(1? ≤?N? ≤? (200000). The next line contains initial state of the array:A0 ,?A1 ,?...,?AN? -? 1 (? -? 106? ≤?AI? ≤? 106 ),AIAre integer. The third line contains integerM(0? ≤?M? ≤? 200000 ),M-The number of operartons. NextMLines contain one operation each. If line contains two integerLf,?RG(0? ≤?Lf,?RG? ≤?N? -? 1) It meansRmqOperation, it contains three IntegersLf,?RG,?V(0? ≤?Lf,?RG? ≤?N? -? 1 ;? -? 106? ≤?V? ≤? 106 )-INCOperation.
Output
For eachRmqOperation Write result for it. please, do not use % LLD specificator to read or write 64-bit integers in C ++. it is preffered to usecout (also you may use % i64d ).

The question is easy to understand.
If A> B, query 0 ~ B and ~ N-1. The rest is the line segment tree Interval Update template, which determines whether C exists in M queries. For details, refer to the Code for better understanding.
