Instructions

Write a program that takes a string number and its string base as arguments and prints its conversion as an int.

• If the base or the string number is not valid it returns 0.

• If the number of arguments is bigger or lower that two it should print a newline ("\n").

Validity rules for a base :

• A base must contain at least 2 characters.
• Each character of a base must be unique.
• A base should not contain + or - characters.

Only valid string numbers will be tested.

The program does not have to manage negative numbers.
