Isomorphic Strings

Given two strings s₁ and s₂, determine whether they are isomorphic.

Two strings are considered isomorphic if the characters in s₁ can be replaced to get s₂, and the mapping between characters is one-to-one and onto. In other words, no two characters in s₁ may map to the same character in s₂, and a character must consistently map to the same character.

For example, "paper" and "title" are isomorphic since the mapping p→t, a→i, e→l, r→e holds, whereas "foo" and "bar" are not isomorphic.

Your task is to write a program which reads two strings from the standard input and prints "Isomorphic" if they satisfy the isomorphism condition, otherwise prints "Not Isomorphic".

inputFormat

The input consists of two lines:

• The first line contains the string s₁.
• The second line contains the string s₂.

outputFormat

Output a single line containing either "Isomorphic" or "Not Isomorphic" based on whether the given strings are isomorphic.
