Kotlin Program:

Example:

*   *   *
  *   *
    *

fun main(args: Array<String>) {
  print("Enter number of rows : ") 
  val userInput = readLine()!!
  var rows:Int =userInput.toInt()
  for(i in 1..rows) {
    for(j in 1..(2*rows-i)) {
      if(j>=i && (j+i)%2==0)print("* ")
      else print("  ")
    }
    println("")
  }
}

Output:

Enter number of rows: 4

*   *   *   *
  *   *   *
    *   *
      *

Main Logic :

for(i in 1..rows) {  //rows : number of rows to print
  for(j in 1..(2*rows-i)) {
    if(j>=i && (j+i)%2==0)print("* ")
    else print("  ")
  }
  println("")
}

You can print any thing in this pattern, just replace your value with *
