Three Exercises - Strings 1. Write a function called squareNumber that will take one argument (a number), square that number, and return the result. It should also log a string like "The result of squaring the number 3 is 9." 2. Create a function called fixStart. It should take a single argument, a string, and return a version where all occurrences of its first character have been replaced with '*', except for the first character itself. You can assume that the string is at least one character long. For example: fixStart('babble'): 'ba**le' 3. Create a function called notBad that takes a single argument, a string. It should find the first appearance of the substring 'not' and 'bad'. If the 'bad' follows the 'not', then it should replace the whole 'not'... 'bad' substring with 'good' and return the result. If it doesn't find 'not' and 'bad' in the right sequence (or at all), just return the original sentence. O For example: notBad('This dinner is not that bad!'): 'This dinner is good!' notBad('This movie is not so bad!'): 'This movie is good!' notBad('This dinner is bad!'): 'This dinner is bad
