What would be the Prefix notation for the given equation?
A+(B*C)
a) +A*CB
b) *B+AC
c) +A*BC
d) *A+CB
Answer: c
Explanation: Reverse the equation or scan the equation from right to left. Apply the infix-postfix algorithm. The equation inside the bracket evaluates to CB* and outside the bracket evaluates to A+ therefore getting CB*A+. Reversing this and we get +A*BC.
