原计算公式:

W_i = (a*i^5+b*i^2+c) mod d 
and   U_i = (e*i^5+f*i^3+g) mod h 
 (0 <= a <= 1,000,000,000; 0 <= b <= 1,000,000,000; 0 <= c <= 1,000,000,000; 0 <= e <= 
1,000,000,000; 0 <= f <= 1,000,000,000; 0 <= g <= 1,000,000,000; 10,000,000 <= d <= 1,000,000,000; 10,000,000 <= h <= 1,000,000,000). 

蒟蒻入门LaTeX瞎写的LaTeX公式:

$W_i=(a\times i^5+b\times i^2+c)\mod d$ $U_i=(e\times i^5+f\times i^3+g)\mod h$ $(0\le a,b,c,d,e,f,g,h\le 1,000,000,000)$
