The Gold-Bug P35941
Consider a text made up of only lowercase letters, which is encrypted with one of the easiest methods: each letter has an associated character that is always written in its place. Given the translation table and the text encrypted with this table, recover the original text.
Input
Input consists of several cases separated by an empty line. Every
case has three parts. The first one is a line with the translation
table: 26 different characters (with no spaces nor ‘_’),
the first one corresponding to ‘a’, the second one to
‘b’, …, and the last one to ‘z’. The second
part is a number
in a line. The third part consists of
encrypted lines of text.
Output
For each case, write the original text, also with
lines. Change each ‘_’ of the encrypted text for a space.
Write an empty line at the end of each case.
Observation
The first example is (basically) extracted from the story “The Gold-Bug” of Edgar Allan Poe. The second text is a famous quotation of Donald Knuth.
