A [[wp:Truth table|truth table]] is a display of the inputs to, and the output of a Boolean function organized as a table where each row gives one combination of input values and the corresponding value of the function.


;Task:
# Input a Boolean function from the user as a string then calculate and print a formatted truth table for the given function.<br> (One can assume that the user input is correct).
# Print and show output for Boolean functions of two and three input variables, but any program should not be limited to that many variables in the function. 
# Either reverse-polish or infix notation expressions are allowed.
