Swift-变位词判断

题目:如果两个单词的组成字母完全相同，只是字母的排列顺序不一样，则它们就是变位词，两个单词相同也被认为是变位词。如tea 与eat , nic 与cin, ddc与dcd, abc与abc.
核心代码:

`
 func isAnagram(first:String,next:String) -> Bool {
 if first == next {
 return true
 }
 
 
    var dict:[String:Int] = [:]
    for i in 0..

测试代码:

`
 
 
var isAnagram:Bool = hashSearch.isAnagram(first: "abca", next: "baccccc")
 print("FlyElephant-是否是变位词---(isAnagram)")`
