[MohamedEbrahem1]

Is your feature request related to a problem? Please describe. The issue is to show the truth table. Describe the solution you'd like

1. make a function evaluateExpression that evaluates any Boolean expression
2. make a function replaceVariables that takes the expression and changes the values of the variables to 0s and 1s
3. make a function expressionIterator to traverse all possible combinations of Logic.
4. iterate over all possible combinations to generate the truth table
