2.the infix form of the postfix expression (AB+CD+/A*B+)is
a.(A+B)*(C+D)/(A+B)
b.B+(A+B)/(C+D)*A
c.(A+B)/(C+D)*(A+B)
d.B+((A+B)/(C+D)*A)
這提稿不懂b跟d有啥差別..不知這兩個要選哪個
5.if X,Y,Z are integer set variables then the expression whose value is the
set of integers in exactly one of the three sets is
a.X*Y*Z
b.X+Y+Z
c.X+Y-Z-Y+Z
d.X+Y+Z*X*Y*Z
這提是再問複雜度嗎？？
