The title ascending number (such as 346 89) refers to a positive integer in which every number in the positive integer is greater than the number to the left of it. It is known that there are a total of 12 6 five-digit “gradual ascents”, if these numbers are reduced from small to large In order of large order, the 10th five-digit gradual ascending number is. To solve this problem, we must solve the following problems: First, understand the concept of “increasing number”. For example, five-digit ascending number 346
