Malek lives in a apartment block with the floors numbered from 0 to 99. The elevator with a digital counter showing the apartment and the elevator on. The elevator shows each digit of a number with 7 light sticks by turning them on or off. The picture below shows how the elevator shows each digit.

One day when Malek wanted to go from floor to floor 0 using the elevator he noticed that the counter shows number Stead of88. Then, the elevator started moving the number on the counter changed to 87. After a little thinking Malek came to the conclusion that there are only one explanation for this:one of the sticks of the Counter was broken. Later that day Malek is thinking about the broken stick and suddenly he came up with the following problem.

Suppose the digital counter is showing number N. Malek calls an integer x (0≤x≤99) Good if it's possible that the Digi Tal counter was supposed to show X but because of some (possibly none) broken sticks it ' s showing n instead. Malek wants to know number of good integers for a specific n. So, must write a program, that calculates, this number. Please note this counter always shows the digits. Input

The only line of input contains exactly the digits representing number n (0≤n≤99). Note that N could have a leading zero. Output

The the only line of the output print the number of good integers. Sample Test (s) input

89

Output

2

Input

00

Output

4

Input

73

Output

15

Note

In the first sample the counter is supposed to show or 89.

In the second sample the good integers is xx, and 88.

In the third sample the good integers is 03, 08, 09, 33, 38, 39, 73, 78, 79, 83, 88, 89, 93, 98, 99.
