Problem Description
There is a youngster known for amateur propositions concerning several mathematical hard problems.
Nowadays, he is preparing a thought-provoking problem on a specific type of supercomputer which has ability to support calculations of integers between 0
and (2m
−1)
(inclusive).
As a young man born with ten fingers, he loves the powers of 10
so much, which results in his eccentricity that he always ranges integers he would like to use from 1
to 10k
(inclusive).
For the sake of processing, all integers he would use possibly in this interesting problem ought to be as computable as this supercomputer could.
Given the positive integer m
, your task is to determine maximum possible integer k
that is suitable for the specific supercomputer.
Input
The input contains multiple test cases. Each test case in one line contains only one positive integer m
, satisfying 1≤m≤105
.
Output
For each test case, output "Case #x
: y
" in one line (without quotes), where x
indicates the case number starting from 1
and y
denotes the answer of corresponding case.
Sample Input
1
64
Sample Output
Case #1: 0
Case #2: 19
