Two strings are isomorphic when characters from s can be replaced to form t with a one-to-one mapping, while preserving the order of characters. Examples Example 1: Input: s = "egg", t = "add" Output: true Example 2: Input: s = "foo", t = "bar" Output: false Constraints 1 <= s.length <= 5 * 10^4 t.length == s.length s and t consist of any valid ASCII characters.
