To print an Hourglass Pattern in Go, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars (*) to form the pattern.
In this example,
printHourglass
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from n
to 1 and the inner loops control the spaces and stars in each row.package main
import (
"fmt"
"strings"
)
func printHourglass(n int) {
for i := n; i >= 1; i-- {
spaces := strings.Repeat(" ", n-i)
stars := strings.Repeat("*", 2*i-1)
fmt.Println(spaces + stars)
}
for i := 2; i <= n; i++ {
spaces := strings.Repeat(" ", n-i)
stars := strings.Repeat("*", 2*i-1)
fmt.Println(spaces + stars)
}
}
// Example usage
func main() {
printHourglass(5)
}
