Infix expression to postfix form using the stack function, Data Structure & Algorithms

Assignment Help:

Q. Convert the following given Infix expression to Postfix form using the stack function: x + y * z + (p * q + r ) * s, Follow general precedence rule and suppose that the expression is legal.                                                                                         

Ans.

The given infix expression is as follows :-

x + y * z + (p * q + r) * s

Symb                Stack                    Postfix Expression x empty  x

+                       +(+                       xyz*+pq*

r                        +(+                       xyz*+pq*r

)                        +                           xyz*+pq*r+

*                       +*                         xyz*+pq*r+

s                        +*                         xyz*+pq*r+s

= xyz*+pq*r+s*+ The postfix expression obtained  is :- xyz*+pq*r+s*+
