Article Introduction：Counting the stages within an integer N, forming an acyclic graph requires investigating every possible variation and checking whether they form an acyclic graph according to a given condition. These conditions may be related to the structure of coordination graphs formed by changes, where the absence of cycles indicates acyclicity. This problem involves concepts from graph theory and can be solved by depth-first search or dynamic programming. Depth-first search works by investigating each stage recursively, and dynamic programming optimizes loops by storing intermediate results. The number of valid stages at last count shows the number of ways in which an integer N can be organized into an acyclic graph that satisfies predetermined conditions. Methods used Depth-first search (DFS) Dynamic programming Depth-first search (DFS) in generating groupings with a given operation In the DFS method, I
