Pro.ID10268 TitleA Simple Problem with Integers Title链接http://10.20.2.8/oj/exercise/problem?problem_id=10268 AC37 Submit113 Ratio32.74% 时间&空间限制描述You have N integers, A1, A2, ... , AN. You need to deal with two kinds of operations. One type of operation is to add some given number to each number in a given interval. The other is to ask for the sum of numbers in a given interval. 输入The first line contains two numbers N and Q. 1 ≤ N, Q ≤ 100000. The second line contains N numbers, the initial values of A1, A2, ... , AN. -1000000000 ≤ Ai ≤ 1000000000. Each of the next Q lines represents an operation. "C a b c" means adding c to each of Aa, Aa+1, ... , Ab. -10000 ≤ c ≤ 10000. "Q a b" means querying the sum of Aa, Aa+1, ... , Ab. 输出Description You have N integers, A1, A2, ... , AN.
