`Sliding` creates a sliding window view of the slice with the specified window size. Returns an empty slice if size is less than or equal to 0 or greater than the slice length. Useful for moving averages, n-grams, and pattern matching.

|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
nums := []int{1, 2, 3, 4, 5}
|
|
fmt.Println(u.Sliding(nums, 3)) // [[1, 2, 3], [2, 3, 4], [3, 4, 5]]
|
|
|
|
// Size 2
|
|
fmt.Println(u.Sliding(nums, 2)) // [[1, 2], [2, 3], [3, 4], [4, 5]]
|
|
|
|
// N-grams for text
|
|
words := []string{"the", "quick", "brown", "fox"}
|
|
bigrams := u.Sliding(words, 2)
|
|
fmt.Println(bigrams) // [["the", "quick"], ["quick", "brown"], ["brown", "fox"]]
|
|
|
|
// Moving average example
|
|
data := []int{10, 20, 30, 40, 50}
|
|
windows := u.Sliding(data, 3)
|
|
for _, window := range windows {
|
|
sum := 0
|
|
for _, v := range window {
|
|
sum += v
|
|
}
|
|
avg := sum / len(window)
|
|
fmt.Printf("Window: %v, Average: %d\n", window, avg)
|
|
}
|
|
// Window: [10 20 30], Average: 20
|
|
// Window: [20 30 40], Average: 30
|
|
// Window: [30 40 50], Average: 40
|
|
}
|
|
```
