    Hello,

    For me the same solution is passing in python but failing in Scala, can someone help me debug it?

        if((n-2)%2==1):
        y=((((k-1)**(n-2-1))-1))//k
        if (x == 1):
            ways = ((y + 1)*(k-1))+((((k-1)*y))*(k-2))
        else:
            ways=((((k-1)*y) + 1)*(k-2))+((y)*(k-1))
    else:
        y = ((((k - 1) ** (n - 2 - 1)) + 1)) // k
        if (x == 1):
            ways = ((y - 1)*(k-1))+(((k-1)*y)*(k-2))
        else:
            ways=((((k-1)*y) - 1)*(k-2))+((y)*(k-1))

        if (n % 2 == 1) {
      val y = (scala.math.pow(k - 1, n - 3).toLong - 1) / k
      if (x == 1) {
        ((y + 1) * (k - 1)) + ((k - 1) * y * (k - 2))
      }
      else {
        ((((k - 1) * y) + 1) * (k - 2)) + (y * (k - 1))
      }
    }
    else {
      val y = (scala.math.pow(k - 1, n - 3).toLong + 1) / k
      if (x == 1) {
        ((y - 1) * (k - 1)) + ((k - 1) * y * (k - 2))
      }
      else {
        ((((k - 1) * y) - 1) * (k - 2)) + (y * (k - 1))
      }
