题目解答:我们设dp[i]表示从i走到100的期望次数,我们可以列出以下方程: 但是因为有蛇的存在,所以方程是无序的,不能从后向前递推,但是我们可以考虑将其化为上面所述的100个方程,然后通过高斯消元求解。 #include<math.h> #include<stdio.h> #include<string.h> #include<algorithm> using namespace std; typ...

给你一个地图10*10,从1到100,问掷骰子的次数的期望,中间会有传送门从a到b。 高斯消元基础题,学了一发板子,x存放多出来的,a存放系数; 要么是dp[i]=(dp[i+1]+...+dp[i+6]+6)/6; 要么是dp[i]=dp[go[i]]; 值得注意的是哪怕是没有dp[i+6]也要加6,因为说了,如果超界那投得次数也要算上...
