HDU 6057 - Kanade's convolution [ FWT ] | 2017 Multi-University Training Contest 3
题意：
给定两个序列 A[0...2^m-1], B[0...2^m-1]
求 C[0...2^m-1] ，满足：
C[k] = ∑[i&j==k] A[i^j] * B[i|j]
m <= 19
分析：
看C[k]的形式与集合卷积的形式接近，故转化式子时主要向普通的集合卷积式方向靠
与三种位运算都相关的结论是 ： i^j + i&j = i|j
设 x = i^j, y = i|j，则显然 k = y-x，且 k 与 x 互成关于 y 的补集，即 k = x^y
再来关心给定(x,y)，符合 x = i^j, y = i|j的(i,j)对的数目
注意到相同的位 i&j 是确定的，x = i^j 是i和j不同的位的数目，这部分谁是 0 谁是 1 不固定
故(i,j)对的数目为 2^bits(x)
此时重写原式： C[k] = ∑ [k == x^y] [k == y-x] A[x]*2^bits(x) * B[y]
设 A'[x] = A[x]*2^bits(x)
由于 [k == x^y]，第二个条件 [k == y-x] 等价于 bits(k) == bits(y) - bits(x)
C[k] = ∑ [k == x^y] [bits(k) == bits(x) - bits(y)] A'[x] * B[y]
将 A,B,C三个数组按 bits 划分：
C[bits(k)][k] = ∑ [k == x^y] A[bits(x)][x]*2^bits(x) * B[bits(y)][y]
最后按不同的维度(bits)做 FWT即可
