Maximum Number of Books

There are multiple (T) bookstores in the area.Each shopkeeper has a list of B integers that represents the cost of each book.You have different pocket money(P) for each bookstore.Write a program to calculate the maximum number of books you can buy in each store with the corresponding pocket money.

Explanation

Given P = 600 and B = [120, 140, 110, 180, 120, 110] with a pocket money of 600, we can buy the books at index 0,1,2,4,5 , whose sum is 120+140+110+120+110 is equal to P.

Given P = 300 and B = [120 110 1300 130] with a pocket money of 300, we can buy the books at index 0,1 whose sum is 120 + 110 and is less than P.

Given P = 100 and B = [220 1000 500 2000] with pocket money of 100, we can't buy any book. So the output should be Retry.

Repeated Numbers

Eren wants to decode a number.After lots of trial and error, he finally figured out that the number is a count of repeated single-digit integers.

Write a program to help Eren print the decoded number given a string of integers N.

Input

The first line contains a string of integers N.

Output

The output contains a single integer representing count of repeated numbers in the input.

Explanation

For N = 212311 ,

1 and 2 are repeated.Therefore, the output is 2.
