Telefon

Mirko and Slavko often talk on phone. Sometimes during the conversation Slavko wish to tell Mirko a number of a third person, which then Mirko writes on a piece of paper. Slavko will tell the number as a string. Once while they were playing, Slavko noticed that Mirko is always writing the numbers in the same form, he writes stripes in the same places. Later when Slavko was telling the number to Mirko, he told him: "I know exactly how you will write that number". Write a program which determines how Mirko has writen the code on the paper, if the form in which he writes down the numbers and digits is known.
