Expert Solution
Explanation

1) WXYZ -+x

----> Hiiii  Here we have  push the W in the stack W .Now Push the X again in the stack X . 

stack elements : W -> X 

push Y and Z again into the stack 

W -> X -> Y -> Z 

Now we have - .Now pop the stack for two elements ( Y - Z) push again in the stack 

stack elements : W ->X -> ( Y  - Z )

Now we have + Hence pop more two elements again 

X + ( Y - Z )

Then push again 

stack elements : W -> [ X + (Y - Z)]

At end we have  x 

Hence we get  infix expression as   -->  W x [ X + ( Y - Z ) ]
