Isomorphic Strings

Given two strings, determine if they are isomorphic. Two strings A and B are isomorphic if the characters in A can be replaced to get B, with each character mapping to a unique character in B and vice versa. Formally, for every character a in A and corresponding character b in B, there exists a bijective mapping between the characters. In other words, the strings must have the same length, and if A[i] = A[j] then B[i] must equal B[j], and conversely.

Your task is to read two strings from the standard input and output True if they are isomorphic, otherwise output False.

inputFormat

The input consists of two lines:

• The first line contains the string A.
• The second line contains the string B.

outputFormat

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