Write a program that reads repeatedly from the keyboard a prefix expression, converts it to a fully parenthesized infix expression, and determines the value of the expression. Your program must use a stack. Assume each entered prefix expression contains only integer numbers and the *, /, +, - operators. After reading and processing a prefix expression, your program should ask the user if he/she wants to enter another expression as shown in the example below. Example: Enter a prefix expression: + 5 * 10 2 | The corresponding infix expression is: (5 + (10 * 2)) and its value is 25 Do you want to enter another expression (Y/N)? Y Enter a prefix expression: / * 3 2 - 7 4 The corresponding infix expression is: ((3 * 2)/(7 - 4)) and its value is 2 Do you want to enter another expression (Y/N)? N

program must use a stack. Assume each entered prefix expression contains only integer numbers
and the *, /, +, - operators. After reading and processing a prefix expression, your program should
ask the user if he/she wants to enter another expression as shown in the example below.
Example:
Enter a prefix expression: + 5 * 10 2
| The corresponding infix expression is: (5 + (10 * 2)) and its value is 25
Do you want to enter another expression (Y/N)? Y
Enter a prefix expression: / * 3 2 - 7 4
The corresponding infix expression is: ((3 * 2)/(7 - 4)) and its value is 2
