Example 3: Input: "Aabb" Output: "bbAa" Explanation: "bbaA" is also a valid answer, but "Aabb" is incorrect. Note that 'A' and 'a' are treated as two different characters. Solution class Solution { public String frequencySort(String s) { Map<Character, Integer> map = new HashMap<...
Swas sorted in some custom order previously. We want to permute the characters ofTso that they match the order thatSwas sorted. More specifically, ifxoccurs beforeyinS, thenxshould occur beforeyin the returned string. Return any permutation ofT(as a string) that satisfies this property. Example...
