Isomorphic Strings Verification

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. ### Constraints - `1 <= s.length <= 5 * 10^4` - `t.length == s.length` - `s` and `t` consist of any valid ascii character. ### Input Format Two space-separated strings `s` and `t` on a single line. ### Output Format Print `true` if isomorphic, otherwise `false`.
