Problem Description

Takahashi is thinking about inputting an integer $ N $ using a keyboard.
Takahashi uses his left hand for the digits 1, 2, 3, 4, 5 and his right hand for the digits 6, 7, 8, 9, 0.
The time it takes for Takahashi to input each digit is as follows:

• When the digit to be input is the first digit of the integer, it takes $ 500 $ms regardless of the digit.
• Otherwise, if the digit to be input is the same as the previous digit, it takes $ 301 $ms.
• If neither of the above conditions are met and the digit to be input is typed with the same hand as the previous digit, it takes $ 210 $ms.
• In all other cases, it takes $ 100 $ms.

The time it takes to input the integer is the sum of the times it takes to input each digit. Calculate how many milliseconds it takes for Takahashi to input the integer $ N $.

Notes/Hints

Constraints

• $1 \leq N < 10^{200000}$
• The leading digit of $ N $ is not $ 0 $.
• $ N $ is an integer.

Sample Explanation 1

• First, it takes $ 500 $ms to input the leading digit 1.
• The next digit is also 1, which is the same as the previous digit, so it takes $ 301 $ms to input it.
• The next digit is 2, which is different from the previous digit but typed with the same hand, so it takes $ 210 $ms to input it.
• The last digit is 0, which is different from the previous digit and typed with a different hand, so it takes $ 100 $ms to input it.
  Therefore, it takes a total of $ 500 + 301 + 210 + 100 = 1111 $ms to input 1120.

Sample Explanation 2

Since $ N $ consists of only one digit, the time it takes to input it is equal to the time it takes to input the leading digit, which is $ 500 $ms.
