Answer the following questions.
(1) When all the integers from 1 to 2007 are multiplied, how many is 0 lined continuously from ones digit?
(2) When all continuous integers from A to B are multiplied, it is expressed as (A,B) that the number other than 0 appears first in the multiplied number checked sequentially from the ones digit.
For example, since 1 x 2 x 3 x 4 x 5 = 120, (1, 5) =2.
(2)-1 Find (1, 10).
(2)-2 Find (121,130).
