Product of Digits Again

Problem code: DIGITS2

  • Submit
  • All submissions

All submissions for this problem are available.

Chef has called on you many times in the past to solve unusual tasks that seem irrelevant to cooking, and today is no different. Today Chef demands that you find integers whose product of digits is equal to a given integer, but in bases besides 10. Given a string S, you are to determine the smallest positive integer I such that there exists a base B>1 for which the product of the digits of I gives the integer represented by S. For example, if S="11", then the smallest I is 8, because the base 3 representation of I is 22, and in base 3 2*2=11.

Formally, your task is this: find the smallest integer I such that there exists an integer B>1 and integers Ai for which:

  • An*Bn+An-1*Bn-1+...+A1*B+A0 = I
  • 0≤Ai<B for all i
  • An≠0
  • An*An-1*...*A1*A0 = Sm*Bm+Sm-1*Bm-1+...+S1*B1+S0, where Sm is the leftmost character of S, and S0 is the rightmost character of S.
  • 0≤Si<B for all i

Input

Input begins with an integer T, the number of test cases (at most 50). Each test case consists of a single line containing a string S comprised of 0-9 and A-Z characters. Characters A-Z represent the decimal values 10-35, respectively. S will have between 1 and 4 characters, and the first character will not be 0.

Output

For each test case, output a single integer on a line, giving the minimum value of I (printed in decimal). It is guaranteed that I will fit in a 64-bit integer.

HELP

Program should read from standard input and write to standard output.

After you submit a solution you can see your results by clicking on the [My Submissions] tab on the problem page. Below are the possible results:

  • Accepted Your program ran successfully and gave a correct answer. If there is a score for the problem, this will be displayed in parenthesis next to the checkmark.
  • Time Limit Exceeded Your program was compiled successfully, but it didn't stop before time limit. Try optimizing your approach.
  • Wrong Answer Your program compiled and ran succesfully but the output did not match the expected output.
  • Runtime Error Your code compiled and ran but encountered an error. The most common reasons are using too much memory or dividing by zero. For the specific error codes see the help section.
  • Compilation Error Your code was unable to compile. When you see this icon, click on it for more information.
