Problem: The input is a sequence of digits consistent of 0-9. We define "increasing subsequence", when the substring consists of consecutive numbers (NOT including equal). For instance, 0369, 3478, 58. Please write a program (using C, Java, PHP, Ruby or Python) to find the longest increasing subsequence of numbers in the given string.

	object IncSeq {
	def main(args: Array[String]) {
	val result = substrLongestIncSeq("333201299823423234")
	println(result) // 0129
	}

	def substrLongestIncSeq(str: String): String = {
	def rec(nums: List[Char], buf: List[Char] = Nil): List[String] =
	nums match {
	case Nil => Nil
