I' trying to move an item from one position to another inside a slice. Go Playground
indexToRemove := 1
indexWhereToInsert := 4
slice := []int{0,1,2,3,4,5,6,7,8,9}
slice = append(slice[:indexToRemove], slice[indexToRemove+1:]...)
fmt.Println("slice:", slice)
newSlice := append(slice[:indexWhereToInsert], 1)
fmt.Println("newSlice:", newSlice)
slice = append(newSlice, slice[indexWhereToInsert:]...)
fmt.Println("slice:", slice)
This produces to following output:
slice: [0 2 3 4 5 6 7 8 9]
newSlice: [0 2 3 4 1]
slice: [0 2 3 4 1 1 6 7 8 9]
But I would expect the output be like this:
slice: [0 2 3 4 5 6 7 8 9]
newSlice: [0 2 3 4 1]
slice: [0 2 3 4 1 **5** 6 7 8 9]
Where is my fault?
