Isomorphic Strings

Two strings s and t are isomorphic if the characters in s can be replaced to get t, preserving order and with a one-to-one mapping.

Return True or False.

Input:

egg
add

Output:

True

Reasoning:

We create two empty mappings to store the character relationships between s and t.
We iterate over the characters in s and t simultaneously, checking if each character in s maps to a unique character in t. In this case, 'e' maps to 'a', 'g' maps to 'd', and the second 'g' still maps to 'd'.
Since the mappings are consistent ('e' to 'a' and 'g' to 'd') and one-to-one, we can conclude that s and t are isomorphic.
The final output is True, indicating that the strings are isomorphic.
