Aninteresting game HDU

Let’s play a game.We add numbers 1,2...n in increasing order from 1 and put them into some sets. 
When we add i,we must create a new set, and put iinto it.And meanwhile we have to bring [i-lowbit(i)+1,i-1] from their original sets, and put them into the new set,too.When we put one integer into a set,it costs us one unit physical strength. But bringing integer from old set does not cost any physical strength. 
After we add 1,2...n,we have q queries now.There are two different kinds of query: 
1 L R:query the cost of strength after we add all of [L,R](1≤L≤R≤n) 
2 x:query the units of strength we cost for putting x(1≤x≤n) into some sets. 

InputThere are several cases,process till end of the input. 
For each case,the first line contains two integers n and q.Then q lines follow.Each line contains one query.The form of query has been shown above. 
n≤10^18,q≤10^5 
OutputFor each query, please output one line containing your answer for this querySample Input

10 2
1 8 9
2 6

Sample Output

9
2

        
 

Hint

lowbit(i) =i&(-i).It means the size of the lowest nonzero bits in binary of i. For example, 610=1102, lowbit(6) =102= 210
When we add 8,we should bring [1,7] and 8 into new set.
When we add 9,we should bring [9,8] (empty) and 9 into new set.
So the first answer is 8+1=9.
When we add 6 and 8,we should put 6 into new sets.
So the second answer is 2. 

        
 
题意：
多组输入，。每一组数据，有一个数字n，和一个数q，
有1~n个数，将i放入集合中同时放入i-lowbit(i)+1~ i 的所有数。
每向集合中放入一个数，就会消耗一点体力值。

然后有q个询问，询问1是，给你一个l和r，问l~r每一个数都加入到集合中，会消耗多少体力值。
2.
1~n中，对每一个数进行加入到集合中的话，数x会被加入多少次。

思路：
把i放入集合就会放入i-lowbit(i)+1~i的所有数
那么一共就是加入i - (i-lowbit(i)+1) +1 个数，即lowbit(i)个数，
那么一个数i消耗的体力值就是lowbit（i）
那么第一问就是让求l~r的lowbit的sum和。

由于数据量很大，我们不能扫一遍算出，
那么我们来分析一下是否可以优化。，
我们知道，lowbit(i)表示的是数字i的二进制最低位代表的十进制数。
例如6的二进制是110，最低位时第2个1，从右向左第2位，代表的十进制时2，（二进制10是十进制的2），那么lowbit（6）就是2。
那么l~r的lowbit的sum和就是，最低位的1在0位置上的数的数量*1（代表的十进制）+ 最低位的1在1位置上的数的数量*2 +.....
那么问题转化为如何快速的求出l~r中最低位的1在第i位的数的数量，
我们知道这样的一个求解方法（容斥的思想）n/(1<<P)-n/(1<<(p+1))就是·1~n中最低位的1在第p位（从右向左数，0开始计位）的数的数量。
那么我们只需要logn来枚举每一位，然后上面的公式即可计算出每一位的数量。

然后我们来看第二个问题，
要找到x在几个集合中，可用x=x+lowbit（x）找出有多少满足条件的x，就能得到集合的个数
