Is there a way to iterate over a slice in reverse in Go?
You can also do:
s := []int{5, 4, 3, 2, 1}
for i := range s {
fmt.Println(s[len(s)-1-i]) // Suggestion: do `last := len(s)-1` before the loop
}
Output:
1
2
3
4
5

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])
}
