Problem

Bob has an array A[] of N integers. Initially, all the elements of the array are zero. Bob asks you to perform Q operations on this array.

There are three types of operations that can be performed:

  1.  1 X: Update the value of A[X] to  2 * A[X] + 1.
  2.  2 X: Update the value A[X] to A[x]/2 , where is Greatest Integer Function.
  3.  3 X Y: Take all the A[i] such that  X <= i <= Y and convert them into their corresponding binary strings. Now concatenate all the binary strings and find the total no. of '1' in the resulting string.

Note: It is guaranteed that there is at least 1 type-3 query in the every test case. All the array elements will fit into 64 bit integers.

Input Format:
First line consists of two space-separated integers N and Q.
Next, Q lines consist of Q operations of either of the 3 types as described above.

Output Format:
For each type-3 query print the answer that is the no. of '1' in the resulting string.

Constraints:
1N,Q500000
1XYN

Explanation

Initially, A=[0,0,0,0,0]

After 1st query, A=[1,0,0,0,0]

After 2nd query, A=[1,1,0,0,0]

After 3rd query, A=[1,1,1,0,0]

For 4th query, no. of '1' in binary representation of A[1]=A[2]=A[3]=1. So, answer=3.

For 5th query, answer is 2.
