文[1]在阐述用“分球入盒”模型解决不相邻排列问题时,提出用插空法求解一类不相邻问题时会出现错误,进而引出新的通法———用“分球入盒”模型解决不相邻排列问题,事实上,若能对这个错误的方法略加改进,仍然能很快捷地求解此类间隔问题,本文对此阐述如何将误法改进成通法,希? In [1], when describing the problem of solving the problem of non-adjacent arrangement with the “ball-in-box” model, it is proposed that when using the interpolation method to solve a class of non-adjacent problems, an error will occur and then a new general method will be elicited--“ The ”ball-in-box" model solves the problem of non-adjacent arrangement. In fact, if this method of error can be slightly improved, such spacing problems can still be solved quickly. This article explains how to improve the mistaken method into a common method. ,hope?
