Find the count of integers from the range [a,b] that can be represented as 2x⋅3y (x≥0,y≥0).
Consists of no more than 106 lines. Each line contains two integers a and b (0≤a≤b≤1018) that represents one query.
For each query print in a separate line the number of integers from the range [a,b] inclusively that can be represented as 2x⋅3y.
