  val userInput = readLine()!!
  var rows:Int =userInput.toInt()
  for(i in rows downTo 1) {
    for(j in 1..(2*rows-i)) {

Main Logic :

for(i in rows downTo 1) {  //rows : number of rows to print
  for(j in 1..(2*rows-i)) {
    if(j<i)print("  ")
    else print("* ")
  }
  println("")
}

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