The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

zemax源码: This DLL models an anamorphic aspheric surface. This surface is essentially an even aspheric surface with different terms for the x and y directions. The sag is given by: Z = ((CX*x*x)+(CY*y*y)) / (1 + sqrt(1-((1+KX)*CX*CX*x*x)-((1+KY)*CY*CY*y*y))) + AR*( (1 - AP)*x*x + (1 + AP)*y*y )^2 + BR*( (1 - BP)*x*x + (1 + BP)*y*y )^3 + CR*( (1 - CP)*x*x + (1 + CP)*y*y )^4 + DR*( (1 - DP)*x*x + (1 + DP)*y*y )^5 Note the terms AR, BR, CR, and DR ... have units of length to the -3, -5, -7, and -9 power. The terms AP, BP, CP, and DP are dimensionless. The surface is rotationally symmetric only if AP = BP = CP = DP == 0 and CX = CY and KX = KY.

上下文无关文法(Context-Free Grammar, CFG)是一个4元组G=(V, T, S, P),其中,V和T是不相交的有限集,S∈V,P是一组有限的产生式规则集,形如A→α,其中A∈V,且α∈(V∪T)*。V的元素称为非终结符,T的元素称为终结符,S是一个特殊的非终结符,称为文法开始符。 设G=(V, T, S, P)是一个CFG,则G产生的语言是所有可由G产生的字符串组成的集合,即L(G)={x∈T* | Sx}。一个语言L是上下文无关语言(Context-Free Language, CFL),当且仅当存在一个CFG G,使得L=L(G)。 *⇒ 例如,设文法G:S→AB A→aA|a B→bB|b 则L(G)={a^nb^m | n,m>=1} 其中非终结符都是大写字母,开始符都是S,终结符都是小写字母。
