How to print Hollow Pyramid Pattern in Kotlin

How to print Hollow Pyramid Pattern in Kotlin ?

Answer

To print a hollow pyramid pattern in Kotlin, you can use nested loops. The outer loop controls the rows, and the inner loops manage the spaces and stars to create the hollow effect.

✐ Examples

1 Hollow Pyramid Pattern of height 5

In this example,

Set the number of rows for the pyramid.
Use nested loops: one for rows, one for spaces, and one for stars.
In the inner loops, print spaces for the spaces between stars and print stars for the pyramid edges.
Adjust conditions to print stars only at the pyramid edges and spaces elsewhere to create the hollow effect.
Print each row to create the hollow pyramid pattern.

Kotlin Program

fun main() {
    val rows = 5
    for (i in 1..rows) {
        // Print spaces
        for (j in i until rows) {
            print("  ")
        }
        // Print stars for the pyramid
        for (k in 1 until (2 * i)) {
            if (k == 1 || k == (2 * i - 1) || i == rows) {
                print("* ")
            } else {
                print("  ")
            }
        }
        println()
    }
}

Output

        * 
      *   * 
    *       * 
  *           * 
* * * * * * * * *
