POJ 3468
A Simple Problem with Integers
Time Limit:5000MS Memory Limit:131072K
Total Submissions:15365 Accepted:3840
Case Time Limit:2000MS
Description
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.
Input
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.
Output
You need to answer all Q commands in order.One answer in a line.
Sample Input
10 51 2 3 4 5 6 7 8 9 10
Q 4 4
Q 1 10
Q 2 4
C 3 6 3
Q 2 4
Sample Output
4 55 9 15
