数论+乱搞——cf181B

/*
2-type B|D^k
3-type B|D-1
11-type B|D+1 
6-type B质因子分解， 
7-type 其他情况 
 
3-type:
    (a*(D^4-1)+b*(D^3-1)+...+d*(D-1)) % B = 0
    B|(D-1)  
11-type:
    (a*(D^4-1)+b*(D^3+1)+c*(D^2-1)+d*(D^1+1)) % B=0
    B|(D^k+(-1)^k)
    k为奇数时，D^k-1因式分解后必然有B|(D+1) 
    k为偶数时，(D+1)(D^(k-1)-D^(k-2)+D^(k-3)...+1),也必有B|(D+1)
    且对于任意的k，(D^k+(-1)^k)只有(D+1)这个公因子
