How to check if a number has zero in the center in Scala

Answer 1

object Main extends App {
  def hasZeroInCenter(number: Int): Boolean = {
    val numStr = number.toString

    if (numStr.length % 2 == 0) {
      false // Even length = no center digit
    } else {
      val centerIndex = numStr.length / 2
      numStr.charAt(centerIndex) == '0'
    }
  }

  val number = 3720961

  if (hasZeroInCenter(number)) {
    println("yes")
  } else {
    println("no")
  }
}
