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.
n=int(input())
for i in range(n):
  number=int(input())
  t=len(str(number))
  count=number%10
  if number<10:
      print(count)
  elif t==2:
      print(9+(number+1-10)*2)
  else:
      count=9
      j=2
      while j<t:
          count=count+((pow(10,j-1))*9*j)
          print(count)
          j+=1
      count=count+(number+1-(pow(10,j-1)))*j
      print(count)
