Write a Go program to print the hollow left pascals triangle star pattern using for loop.
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() } }
This Go example prints the hollow left pascals triangle of a given character.
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() } }
Enter Hollow Left Pascals Star Pattern Rows = 15
