DP, the state is F[I][J][K1][K2], for the first person, with J Boys, the suffix of boys more than the number of girls in the maximum value of K1, girls more than the number of boys maximum is k2.k1,k2 State transition equation F[i][j][k1][k2] = f[i-1][j-1][k1+1][k2-1] + f[i-1][j][k1-1][k2+1]. The premises are legal. The answer is F[N+M][N][K1][K2]. 0 Need to use a scrolling array, the last launch of Next, because swap, became cur, so the output is cur. #include #include#includeusing namespacestd
