Golang 面试题 (2) 大切片分割成指定大小的小切片

Golang面试编程题2

实现一个函数可以根据指定的size切割切片为多个小切片

func main() {
	lenth := 11
	size := 5
	list := make([]int, 0, lenth)
	for i := 0; i < lenth; i++ {
		list = append(list, i)
	}
	SpiltList(list, size)
}

func SpiltList(list []int, size int) {
	lens := len(list)
	mod := math.Ceil(float64(lens) / float64(size))
	fmt.Println(mod) // 3
	spliltList := make([][]int, 0)
	for i := 0; i < int(mod); i++ {
		tmpList := make([]int, 0, size)
		fmt.Println("i=", i)
		if i == int(mod)-1 {
			tmpList = list[i*size:]
		} else {
			tmpList = list[i*size : i*size+size]
		}
		spliltList = append(spliltList, tmpList)
	}
	for i, sp := range spliltList {
		fmt.Println(i, " ==> ", sp)
	}
}

3
i= 0
i= 1
i= 2
0  ==>  [0 1 2 3 4]
1  ==>  [5 6 7 8 9]
2  ==>  [10]
