CodeForces960DFull Binary Tree Queries(二叉樹的操作)

Full Binary Tree Queries

You have a full binary tree having infinite levels.

Each node has an initial value. If a node has value x, then its left child has value 2·x and its right child has value 2·x + 1.

The value of the root is 1.

You need to answer Q queries.

There are 3 types of queries:

1. Cyclically shift the values of all nodes on the same level as node with value X by K units. (The values/nodes of any other level are not affected).
2. Cyclically shift the nodes on the same level as node with value X by K units. (The subtrees of these nodes will move along with them).
3. Print the value of every node encountered on the simple path from the node with value X to the root.

Positive K implies right cyclic shift and negative K implies left cyclic shift.

It is guaranteed that atleast one type 3 query is present.

Input

The first line contains a single integer Q (1 ≤ Q ≤ 105).

Then Q queries follow, one per line:

• Queries of type 1 and 2 have the following format: T X K (1 ≤ T ≤ 2; 1 ≤ X ≤ 1018; 0 ≤ |K| ≤ 1018), where T is type of the query.
• Queries of type 3 have the following format: 3 X (1 ≤ X ≤ 1018).

Output

For each query of type 3, print the values of all nodes encountered in descending order.

Examples input Copy

5
3 12
1 2 1
3 12
2 4 -1
3 8
      

output Copy

12 6 3 1 
12 6 2 1 
8 4 2 1 
      

input Copy

output Copy

14 6 2 1 
      

Note

Following are the images of the first 4 levels of the tree in the first test case:

題意：無限長度的二叉樹,每次操作1把包含數x的那一層整體移動k個位置，正往右，負往左，操作2把包含數x的那一層帶着子樹移動k個位置.操作3列印從x到根沿線的所有數.

思路：對于每一層我們可以記錄旋轉了多少次,因為最多有60+層.對于操作2它的子樹就分别移動k^2次,k^4次...，對于查詢操作,我們可以先找到x的位置，然後依次除以2就是上層的對應位置,根據旋轉次數列印相應數字即可.

代碼：

#define mem(a,b) memset(a,b,sizeof(a))
#define mod 1000000007

ll c[110];

{
	c[1] = 1;

		c[i] = c[i-1]*2;
