Q12 - Echo a Response (0.5 points) We will define a function that will return a string that has been repeated a specified number of times, with a given separator. We will also want to deal with the case where the input to this function may be None. Write a function called respond_echo. This function should have the following inputs, outputs, and internal procedures: Input(s): input_string - string, or None number_of_echoes - integer spacer - string Output(s): echo_output - string, or None Procedure(s): if input_string is not None: set a variable echo_output to be input_string, repeated the number of times specified by number_of_echoes, joined by the spacer. Hint: to do so, recall what "*" does to strings otherwise (if input_string is None): set echo_output to None return echo_output Note that a simple version of this function will end up appending the spacer to the end of the list as well. For our purposes here, implement that simple version.

For this assignment you have to write a c program that will take an infix expression as input and display the postfix expression of the input. after converting to the postfix expression, the program should evaluate the expression from the postfix and display the result. what should you submit? write all the code in a single file and upload the .c file. compliance with rules: ucf golden rules apply towards this assignment and submission. assignment rules mentioned in syllabus, are also applied in this submission. the ta and instructor can call any students for explaining any part of the code in order to better assess your authorship and for further clarification if needed. problem: we as humans write math expression in infix notation, e.g. 5 + 2 (the operators are written in-between the operands). in computer's language, however, it is preferred to have the operators on the right side of the operands, ie. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix write a program that takes an "infix" expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % ( example infix expression: (7-3)/(2+2) postfix expression: 7 3 2 2 result: rubric: 1) if code does not compile in eustis server: 0. 2) checking the balance of the parenthesis: 2 points 3) incorrect postfix expression per test case: -2 points 4) correct postfix but incorrect evaluation per test case: -i points 5) handling single digit inputs: maximum 11 points 6) handling two-digit inputs: 100 percent (if pass all test cases)
