`Reduce` combine a list of values into a single value. `acc` is the initial state, and each successive step of it should
be returned by the reduction function.
```go
package main
import (
"fmt"
u "github.com/rjNemo/underscore"
)
func main() {
nums := []int{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
sum := func(n, acc int) int { return n + acc }
fmt.Println(u.Reduce(nums, sum, 0)) // 45
}
```
