abc232_e Rook Path

https://atcoder.jp/contests/abc232/tasks/abc232_e
国际象棋棋盘
一个车
从x1 y1 走到x2 y2
走恰好k步，问方案数

最基本的动态规划：
f[k][i][j] 走到 (i, j) 恰好k步的方案数
for (k=0 to 步数)
    for i 每行
        for j 每列
            f[k][i][j] = 0
            for (x, y) 和 (i, j) 在同一行或同一列，但不是 (i, j)
                f[k][i][j] += f[k-1][x][y]

（步数+1，行数，列数）
因为步数从0开始
注意到 f[k] 是 H * W 的数组，数组里只有4种值
(x1, y1)
(x1, 非y1)
(非x1, y1)
(非x1, 非y1)
实际上不需要维护 H * W 的数组，只需要维护这四个值就可以了

0 1 0
0 0 0

1 0 1
0 1 0

1 3 1
2 0 2

6 2 6
3 7 3

未优化：
f[3][2][1] = 3
f[3][2][3] = 3

优化后：
f[3][非x1 非y1] = 3

H 行 W 列
(x1,y1) = (x1,非y1) * (W-1) + (非x1,y1) * (H-1)
(x1,非y1) = (x1,非y1) * (W-2) + (x1,y1) + (非x1,非y1) * (H-1)
(非x1,y1) = (非x1,y1) * (H-2) + (x1,y1) + (非x1,非y1) * (W-1)
(非x1,非y1) = (非x1,非y1) * (H+W-4) + (非x1,y1) + (x1,非y1)

注意到 H>=2 W>=2 所以没什么特殊情况
最后根据 x2是否等于x1 y2是否等于y1 决定输出四个中的哪个

abc232_f Simple Operations on Sequence

https://atcoder.jp/contests/abc232/tasks/abc232_f
输入两个数组，A和B

可以交换两个相邻的元素，花费Y的代价
问最小代价是什么

核心是决定A的一个排列（代价：交换次数 * Y）
和B比较，代价是对应的位置绝对值的差 * X
核心就是用一个数字表示一个集合

f[A中用了哪些数字]  匹配B中前几个数字
for (每个集合i)
    for (不在集合中的j)
        f[集合i 并 元素j] = min(f[集合i 并 元素j],
            f[i] + abs(a[j]-b[该第几个元素了])*Y + 交换次数*X)
cout << f[全集] <<endl;

提交做题，一共有N组数据
其中M组，每一组正确的概率是1/2
另外N-M组，正确概率是1
提交一次消耗M*1900+(N-M)*100的时间
消耗的时间是固定的，和自己对几个，错几个没有关系
问期望需要多少时间通过所有N个测试点？

因为消耗的时间和对几个错几个没关系，所以答案就是期望提交次数乘以每次提交的时间
如果提交一次，有1/2的概率正确，那么期望交2次
如果提交一次，有1/4的概率正确，那么期望交4次
如果提交一次，有1/8的概率正确，那么期望交8次
如果提交一次，有1/2**m的概率正确，那么期望交2**m次
