Vanya got an important task — he should enumerate books in the library and label each book with its number. Each of the *n* books should be assigned with a number from 1 to *n*. Naturally, distinct books should be assigned distinct numbers.

Vanya wants to know how many digits he will have to write down as he labels the books.
The first line contains integer *n* (1 ≤ *n* ≤ 10<sup class="upper-index">9</sup>) — the number of books in the library.
s=(input())
num=int(s)
# import sys
# for i in range(int(input())):
    # arr=list(map(int,input().split()))
    # a,b,x,y=map(int,input().split())
n=len(s)
if num<10:
    print(num)
    exit()
ans=0
val=int("1"+(n-1)*"0")
ans+=(num-val)*n
print(ans)
for i in range(1,n):
    ans+=i*int("9"+(n-2)*"0")
print(ans)
