Akku likes binary numbers and she likes playing with these numbers. Her teacher once gave her a question.For given value of  L and R, Akku have to find the count of number X, which have only three-set bits in it's binary representation such that "L <= X <= R".Akku is genius, she solved the problem easily. Can you do it ??


The first line of input contains of an integer T i.e number of test cases. Next T lines contains  two space seperated integers L,R


Output consists of T lines each indicating the answer for each test case.


1 <= T <= 10000
1 <= L <= R <= 10^18


Sample Input :

11 19

Sample Output :


Explanation :

There are 4 such numbers with 3 set bits in range 11 to 19.

11 -> 1011

13 -> 1101

14 -> 1110

19 -> 10011
