首先对每个string转换成char array然后排下序,HashMap里面的key存sort后的词,value存原始的词。然后如果这个排好序的词没在HashMap中出现过,那么就把这个sorted word和unsortedword put进HashMap里面。如果一个sorted word是在HashMap里面存在过的,说明这个词肯定是个变形词,除了把这个词加入到返回结果中,还需要把之...

Java Anagrams Arrays.sort(a); Arrays.sort(b); return Arrays.equals(a,b); may look like a fine solution but it’s not. A good code is a fast code, not a short code. If you look in the API, Arrays.sort(a) works in n log(n), another Arrays.sort(a), and we have n log(n...
