evaluate given Prefix notation : *-50 -* 2 +2 3 * 5 4 2

Expert Solution

Step 1

Introduction

Prefix: If the operator appears in an expression before the operands, it is referred to as a prefix expression. of the simplest type (operator operand1 operand2).

Reverse the order of reading the Prefix expression (from right to left)
Push the symbol into the stack if it is an operand.
Pop two operands off the stack if indeed the symbol is just an operator.
Concatenate the two operands with the operator that comes after them to produce a string.
string = operator, operator2, and operand1
And then return the finished string to the stack.
Until the Prefix expression is finished, repeat the previous stages.
