显然是BFS找最优解，可是终止条件不好写，看到有一只队交上去一直TLE。
比赛完了看题解原来是以目标状态为起点，BFS给每个状态打表，用一个map映射存起来。

HDU 1098 Ignatius's puzzle（数论-其它）
题目大意：
给定一个k，找到最小的a 使得 f(x)=5*x^13+13*x^5+k*a*x ，f(x)%65永远等于0
解题思路：
因为 f(x+1)=5*(x+1)^13+13*(x+1)^5+k*a*x，
所以 f(x+1)=f (x) + 5*( (13 1 ) x^12 ...... .....+(13 13) x^0 )+ 13*( (5 1 )x^4+...........+ ( 5 5 )x^0 ...
