使用数组来打印杨辉三角
根据上一行的内容,来获取下一行的内容并打印出来。
package main import "fmt" func GetYangHuiTriangleNextLine(inArr []int) []int { var out []int var i int arrLen := len(inArr) out = append(out, 1) if 0 == arrLen { return out } for i = 0; i < arrLen-1; i++ { out = append(out, inArr[i]+inArr[i+1]) } out = append(out, 1) return out } func main() { nums := []int{} var i int for i = 0; i < 10; i++ { nums = GetYangHuiTriangleNextLine(nums) fmt.Println(nums) } }
输出结果为:
[1] [1 1] [1 2 1] [1 3 3 1] [1 4 6 4 1] [1 5 10 10 5 1] [1 6 15 20 15 6 1] [1 7 21 35 35 21 7 1] [1 8 28 56 70 56 28 8 1] [1 9 36 84 126 126 84 36 9 1]
