FACTBASE - Count Zero
Count the zero at the end of N! when represented in base b.
Input
the first line is the number T (1 <= T <= 10^5)
the Ith line in the T line contains two positive integers N (1 <= N <= 10^18), b (2 <= b <= 10^6)
Output
Consists of T lines, the Ith line is the result of the test i
Example
Input: 6 3 7 5 2 10 3 10 9 1000 2 1000 30 Output: 0 3 4 2 994 249

@:C++: You got TLE or WA on 8/10 of input files. So a score of 20%.

I still think this one belongs to classical, and need better judge.

We should waiting for something like a week, read others opinion, and hope return to classical with default judge (and rejudge). If nothing is done within a week, we'll can consider a harder edition. Any other suggestions ? |

I agree with Francky, but the judge seems still crash (sometimes get 0k mem and 0 pts) so if change the scoring to binary, it will accept all submissions, so my suggestion is create new problem like this (with default judge).. Last edit: 2013-01-28 16:11:41 |

I made a terrible mistake in considering this one as a simple variant of FCTRL. It's not and I must apologize for my first (deleted) comments where I suggested it was tutorial, now I think it belongs to classical. Not so hard, but classical. Thanks for this problem. Sorry again for my first comment.

@Francky: No, the example is correct (based on my program, My output match the example given).. |
