跳过Golang中数组的第一个元素

Question

I have the following code segments

for _, val := range Arr {
    // something have to do with val
}

In Arr , there might be more than 1 elements. I want to skip the first element of Arr and continue the loop from the second element.

For example if Arr contains {1,2,3,4}. With the query I just want to take {2,3,4}.

Is there a way to do that with the range query ?

Answer 1

Yes. Use this

for _, val := range Arr[1:] {
// something have to do with val
}

Or

s = len(Arr)
for _, val := range Arr[1:s] {
// something have to do with val
}
