Go Slice Distribution Example

package main

import "fmt"

// Divides `slice` into `n` subslices such that the elements are distributed
// as evenly as possible. In other words, if there are 10 elements in `slice`,
// and `n` is 3, there will be one subslice with 4 elements and the others will
// have only 3.
func subslice(s []interface{}, n int)(ret [][]interface{}){
	for ; n > 0; n-- {
		s, ret = s[len(s)/n:], append(ret, s[:len(s)/n])
	}
	return ret
}

func main() {
	fmt.Println(subslice([]interface{}{"a","b","c",1,2,3}, 4))
