有没有办法在Go中反向切片？ [英] Is there a way to iterate over a slice in reverse in Go?

问题描述

  for _，反向范围内的元素mySlice {
 ... 
} 
  

解决方案

否没有方便的操作员为此添加一个到位的范围。你必须做一个正常的循环倒计数：

  s：= [] int {5，4，3， 2，1} 
 for i：= len（s）-1; i> = 0; i-- {
 fmt.Println（s [i]）
} 
  

It would be convenient to be able to say something like:

for _, element in reverse range mySlice {
        ...
}

解决方案

No there is no convenient operator for this to add to the range one in place. You'll have to do a normal for loop counting down:

s := []int{5, 4, 3, 2, 1}
for i := len(s)-1; i >= 0; i-- {
   fmt.Println(s[i])
}
