Today is August 24, one of the five Product Days in a year.  A date m-d (m is the month, d is the date) is called a Product Day when d is a two-digit number, and all of the following conditions are satisfied (here d_{10} is the tens digit of the day and d_1 is the ones digit of the day):    * d_1 \geq 2   * d_{10} \geq 2   * d_1 \times d_{10} = m  Takahashi wants more Product Days, and he made a new calendar called Takahashi Calendar where a year consists of M month from Month 1 to Month M, and each month consists of D days from Day 1 to Day D.  In Takahashi Calendar, how many Product Days does a year have?
