Logical Operators

Learn methods that simulate logical operators which are used to parse sentences.

The NOT operator

In this lesson, we’ll try to simulate the NOT operator in the parsing process. This operator can be useful when we need to analyze portions from the input string different from some predefined string values. We need to implement a method that takes an array of strings as a parameter and returns a function that takes the input string and the cursor. Below is the implementation of the method.

Note: We can enter any string value as an input at the bottom of the widget to run the code.
