P3374 "template" tree Array 1 title description

Title, you need to perform the following two operations, known as a sequence:

1. Add a number to the X

2. Find out the amount of each number in a range and

Input/output format Input Format:

The first line contains two integers n, M, respectively, indicating the number of numbers and the total number of operations.

The second line contains n space-delimited integers, where the I number represents the initial value of item I of a sequence.

The next M line contains 3 or 4 integers, representing an operation, as follows:

Action 1: Format: 1 x k Meaning: Add x number plus K

Action 2: Format: 2 x y meaning: the and of each number in the output interval [x, y]

output Format:

The output contains several line integers, which is the result of all Operation 2.
