1153. String Transforms Into Another String

Leetcode Solutions

Initialize a hashmap conversionMappings to store the character mappings from str1 to str2.
Initialize a hashset uniqueCharactersInStr2 to store the unique characters in str2.
Iterate over the characters in str1.
- If the current character is not in conversionMappings, add the mapping to conversionMappings and add the corresponding character in str2 to uniqueCharactersInStr2.
- If the current character is already in conversionMappings but maps to a different character than the current character in str2, return false.
After the iteration, if uniqueCharactersInStr2 contains 26 characters and str1 is not equal to str2, return false. Otherwise, return true.
