Design a Context free grammar that contains equal number of a's and b's over input {a,b} i.e. no(a)=no(b)

 Design a Context free grammar that contains equal number of a's and b's over input {a,b} i.e. no(a)=no(b)

Answer-

The Context free grammar (G)=(V,Σ,P,S)

Where 

V={S}

Σ={a,b}

P={S→aSbS|bSaS|λ}

S={S}

  Write Pseudocode and draw flow chart of the following problem . The python program allows the user to enter the Sales amount and Actual cost of a Product. Next, Python calculates the Loss Amount or profit Amount based on those two values using if-elif-else Statement. Answer- Pseudocode Input the Actual cost of  Product Input the Sales Amount if(actual_cost > sale_amount):     amount = actual_cost - sale_amount     print("Total Loss Amount") elif(sale_amount > actual_cost):     amount = sale_amount - actual_cost     print("Total Profit ") else:     print("No Profit No Loss!!!") Flow chart- Python Code- #Input Actual cost of  Product actual_cost = float(input(" Please Enter the Actual cost of  Product:")) # Input Sales Amount sale_amount = float(input(" Please Enter the Sales Amount: ")) #calculate Loss Amount if(actual_cost > sale_amount):     amount = actual_cost - sale_amount     print("Total Loss Amount = {0}".for
