Given two strings s and t, determine if they are isomorphic.
Two strings s and t are isomorphic if the characters in s can be replaced to get t.
All occurrences of a character must be replaced with another character while preserving the order of characters. No two characters may map to the same character, but a character may map to itself.
class Solution:
def isIsomorphic(self, s: str, t: str) -> bool:
for i in range(len(s)):
if s.index(s[i]) != t.index(t[i]):
return False
return True
