bool-calc – Boolean calculator
Write a program that reads several boolean operations and prints their result.
Input will consist of several lines each containing
a boolean operation.
This operation may be unary, in this case
the input line will contain the word not followed by a boolean p.
This operation may be binary, in this case
the input line will contain a boolean p, an operator x and a boolean q.
Input tokens are separated by a single space.
Booleans p and q are either of the strings true or false
and the operator x is either of the strings and, or, xor or implies.
Output should contain a line with the result of the given input operation.
Example input
true and false
false or true
not true
true xor true
true implies true
Example output
false
true
false
false
true
Scoring
- 1/6: works for the above example but produces output in an incorrect format
- 2/6: works for the above example and produces output in the correct format
- 6/6: works for other test cases
