задача от google code jam

как же я зла!!! дали задачу от гугл джем( типа "на!порешай"). решила...но почему-то последние данные, ну никак не хотели "вставать" на место...

решила, что наверное в моей проге где-то косяк... зафигачила другой алгоритм...но нет!!! нифига!!! все равно мои выходные данные остались неизменными.... ну, чтож, стало быть или у меня, или в самой задаче есть ошибка.и начала фигачить на листочке. оказалось, что у меня глаза не там где надо...я не увидела точку в конце входных данных... }:-|

кому стало интересно вот та злосчастная задача:

Alien Numbers

The decimal numeral system is composed of ten digits, which we represent as "0123456789" (the digits in a system are written from lowest to highest). Imagine you have discovered an alien numeral system composed of some number of digits, which may or may not be the same as those used in decimal. For example, if the alien numeral system were represented as "oF8", then the numbers one through ten would be (F, 8, Fo, FF, F8, 8o, 8F, 88, Foo, FoF). We would like to be able to work with numbers in arbitrary alien systems. More generally, we want to be able to convert an arbitrary number that's written in one alien system into a second alien system.


The first line of input gives the number of cases, N. N test cases follow. Each case is a line formatted as

alien_number source_language target_languageEach language will be represented by a list of its digits, ordered from lowest to highest value. No digit will be repeated in any representation, all digits in the alien number will be present in the source language, and the first digit of the alien number will not be the lowest valued digit of the source language (in other words, the alien numbers have no leading zeroes). Each digit will either be a number 0-9, an uppercase or lowercase letter, or one of the following symbols !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~


For each test case, output one line containing "Case #x: " followed by the alien number translated from the source language to the target language.


1 ≤ N ≤ 100.

Small dataset

1 ≤ num digits in alien_number ≤ 4,
2 ≤ num digits in source_language ≤ 10,
2 ≤ num digits in target_language ≤ 10.

Large dataset

1 ≤ alien_number (in decimal) ≤ 1000000000,
2 ≤ num digits in source_language ≤ 94,
2 ≤ num digits in target_language ≤ 94.
