Problem Statement

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?

Constraints

All values in input are integers.

1 \leq M \leq 100

1 \leq D \leq 99

Input

Input is given from Standard Input in the following format:

M D

Output

Print the number of Product Days in a year in Takahashi Calender.

Sample Input 1

15 40

Sample Output 1

10

There are 10 Product Days in a year, as follows (m-d denotes Month m, Day d):

4-22

6-23

6-32

8-24

9-33

10-25

12-26

12-34

14-27

Solution in C (Clang 3.8.0) (judge verdict: Wrong Answer)

#include	<stdio.h>
int main(){
int month=0,day=0,count=0,tmp=0,compare1=0,test=0,compare2=0;
scanf("%d",&month);//tuki
scanf("%d",&day);//hiniti
for(int j=1;j<=month;j++){
for(int i=2;i<10;i++){
	tmp=j/i;
  	test=j%i;
  	compare1=tmp*10+i;
    compare2=i*10+tmp;
  	if(compare1<=day && compare1!=compare2&&tmp<10 && 1<tmp && test==0){
    count=count+1;
     
    }
    if(compare2<=day && tmp<10 && 1<tmp &&test==0){
    count=count+1;
      
    }
}}
printf("%d",count);
 return 0;
}
