Title Description:

There are two dates, ask two days between dates, if two dates are contiguous we stipulate that the number of days between them is two days

Input:

There are more than one set of data, each set of data has two lines, representing two dates, in the form of YYYYMMDD

Output:

One row for each set of data, that is, the date difference value

Sample input:

2011041220110422

Sample output:

11
