Write a program to convert an infix expression to a postfix expression and use it to evaluate a mathematical expression entered by a user. For example, if a user enters the following formula: "2*(3+4)*5", then your program should output the correct result of 70. Several examples of input expressions and their corresponding output results are shown in the table below. Output results Input expressions 2* (3+4)*5 (2+8)/5 +3-6*9 2+ ((8+12) / 10 - 3) * 5 20 (5 (3+(80/20)) + 6) 60/3+ (9-3)* 100 70 -49 -3 -21 620
