sum of coins

You are given a directed tree with N with nodes numbered 1 to N and root at node 1. Each node initially contains 0 coins.

You have to handle a total of M operations:
1 L Y : Increase by Y the coins of all nodes which are at a distance L from root.
2 X : Report the sum of coins of all nodes in subtree rooted at node X.

Input

First line contains N and M.
Each of the next N-1 lines contains u and v denoting directed edge from node numbered u to v.
Each of the next M lines contain queries of either Type 1 or 2.

Output

For each query of Type 2, print the required sum.

Constraints

Should contain all the constraints on the input data that you may have. Format it like:

  • 1 = N = 105
  • 1 = M = 104
  • 0 = L =Maximum height of tree
  • 0 = Y = 109
  • 1 = X, u, v = N

 

Example

Input: 5 4 1 2 1 3 3 4 3 5 1 1 2 1 2 3 2 3 2 1 Output: 8 10

 

Explanation

In first update nodes 2 and 3 are increased by 2 coins each.
In second update nodes 4 and 5 are increased by 3 each.
