Go语言打印空心左侧帕斯卡星形三角形的程序

编写一个Go程序，使用for循环打印空心左侧帕斯卡三角形星形图案。

package main

import "fmt"

func main() {

	var i, j, k, row int

	fmt.Print("Enter Hollow Left Pascals Star Pattern Rows = ")
	fmt.Scanln(&row)

	fmt.Println("Hollow Left Pascals Star Triangle Pattern")

	for i = 1; i <= row; i++ {
		for j = row; j > i; j-- {
			fmt.Printf(" ")
		}
		for k = 1; k <= i; k++ {
			if k == 1 || k == i {
				fmt.Printf("*")
			} else {
				fmt.Printf(" ")
			}
		}
		fmt.Println()
	}

	for i = 1; i <= row-1; i++ {
		for j = 1; j <= i; j++ {
			fmt.Printf(" ")
		}
		for k = row - 1; k >= i; k-- {
			if k == row-1 || k == i {
				fmt.Printf("*")
			} else {
				fmt.Printf(" ")
			}
		}
		fmt.Println()
	}
}

这个 Go示例 打印指定字符的空心左侧帕斯卡三角形。

package main

import (
	"bufio"
	"fmt"
	"os"
)

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, k, row int

	fmt.Print("Enter Hollow Left Pascals Star Pattern Rows = ")
	fmt.Scanln(&row)

	fmt.Print("Character to Print in Hollow Left Pascals Triangle = ")
	ch, _, _ := reader.ReadRune()

	fmt.Println("Hollow Left Pascals Triangle Pattern")

	for i = 1; i <= row; i++ {
		for j = row; j > i; j-- {
			fmt.Printf(" ")
		}
		for k = 1; k <= i; k++ {
			if k == 1 || k == i {
				fmt.Printf("%c", ch)
			} else {
				fmt.Printf(" ")
			}
		}
		fmt.Println()
	}

	for i = 1; i <= row-1; i++ {
		for j = 1; j <= i; j++ {
			fmt.Printf(" ")
		}
		for k = row - 1; k >= i; k-- {
			if k == row-1 || k == i {
				fmt.Printf("%c", ch)
			} else {
				fmt.Printf(" ")
			}
		}
		fmt.Println()
	}
}
