暴力枚举ab的值，在o(1)内把c算出来，看一下是否合法就行，最大值可以打表找规律发现是17+8*(n-1)

D、 Logo Turtle
一个T和F的字符串，你可以把任意元素翻转任意次，一共有n次翻转机会，翻转就是T变F，F变T
F是前进一步，T是回头，问你n次翻转之后最终抵达的终点到原点的距离最大是多少
考虑三维dp[i][j][1/0]，第三维是朝向，前两维代表前i个字符翻转j次的答案
枚举当前字符的翻转次数k
如果翻成了T，那么dp[i][j][0]=dp[i-1][j-k][1],dp[i][j][1]=dp[i-1][j-k][0]
如果翻成了F，那么dp[i][[j][1]=dp[i-1][j-k][1]+1,dp[i][j][0]=dp[i-1][j-k][0]-1
这里很神秘，注意正方向上的前进等于负方向上的后退
