Isomorphic Strings Checker

Given two strings s₁ and s₂, determine if they are isomorphic. Two strings are isomorphic if there exists a one-to-one mapping between every character of the first string to a character of the second string such that the order is preserved. In other words,

$$\forall i,j,\; (s_{1,i} = s_{1,j} \iff s_{2,i} = s_{2,j})$$

Your task is to write a program that reads the two strings from standard input and prints True if the strings are isomorphic, and False otherwise.

inputFormat

The input consists of two lines:

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

Both strings can contain any printable characters.

outputFormat

Output a single line: True if the two strings are isomorphic, and False otherwise.
