PYTHON

b) Truth-table inputs The function makettins(n) will create a truth table for all combinations of n Boolean variables. A truth table is an arrayList of 2**n arrayLists of n Booleans. For example makettins(2) returns
[[False, False], [False, True], [True, False], [True, True]]

Notice the recursive nature of makettins(n): It consists of a truth-table(n-1), each row prefixed with False followed by the same truth-table(n-1), each row prefixed with True, with a base case for n==1: [[False], [True]]

Two functions are provided: run(f) and main, so that you can test your code.

This can be iterative or recursive.

Answer #1

Find the method to print the truth table below:

1. def print_truth_table(length):
2.    no_of_rows = length ** 2 - 1    
3.    widest_number = len(str(bin(no_of_rows)[2:]))
4.    for i in range(no_of_rows):
5.        the_binary_number = bin(i)[2:].zfill(widest_number)
6.        string = (str(the_binary_number)).replace("0", " False").replace("1", " True")
7.        print(list(string.split(" ")[1:]))

Line no 1 is the method definition.

In line 2 we get the number of rows to print.

Line no 3 is to get the width to make proper binary orientation.

Line no 4 to 7 prints the truth table in the form of True and False.

Thanks!

Please follow ALL the instructions and solve it by C++. Please and thank you! There are two ways to write loops: (1) iterative, like the for-loops we're used to using, and (2) recursive. Your prerequisite preparation for this course should have exposed you to both, although your working knowledge of recursive loops may not be as strong as that of iterative loops. Consider the following iterative function that prints an array of characters backward: #include <iostream> #include <cstring> // print...

A state's Department of Motor Vehicles needs a program to generate license plate numbers. A license plate number consists of three letters followed by three digits, as in CBJ523. (So "number" is a bit inaccurate, but that's the standard word used for license plates). The plate numbers are given out in sequence, so given the current number, the program should output the next number. If the input is CBJ523, the output should be CBJ524. If the input is CBJ999, the...
