Number Isomorphism

CodeChefOpen on judge ↗

Let's call two numbers isomorphic if they have same number of digits and set of places having equal digits is same. We consider that all the numbers are in decimal notation and don't have leading zeroes. Consider some examples: - 12321 is isomorphic to 83538 and 45654. - 1232 is not isomorphically equal to 2342 because set of places having equal digits are {{1}, {2, 4}, {3}} and {{1, 4}, {2}, {
