Golang实现字符串倒序的几种解决方案

  length := len(str)
  array := make([]string , length)
  for i , v := range str{
   array[i] = string(v)
  }
  for i := 0 ; i < length/2 ; i++ {
   array[i], array[length -i - 1] = array[length - i -1 ], array[i]
  }
  str = ""
  for _ , v := range array {
   str += v
  }

 bytes := []rune(str)
 for from , to := 0 , len(bytes) -1 ; from < to ; from , to = from + 1, to -1{
  bytes[from] , bytes[to] = bytes[to] , bytes[from]
 }
 str = string(bytes)
 return str

 bytes := []rune(str)
 for from , to := 0 , len(bytes) -1 ; from < to ; from , to = from + 1, to -1{
  bytes[from] , bytes[to] = bytes[to] , bytes[from]
 }
 str = string(bytes)
 return str
