Problem Set #2 Requirements Write a function firstReverse that takes a single string parameter and returns the string in reverse order. Write a function swapCase that takes a single string parameter and swaps the case of each character. For example: if a string is "Hello World" the output should be "hELLO wORLD". Let numbers and symbols stay the way they are. Bonus: Write a function letterCount that takes a single string parameter and returns the first word with the greatest number of repeated letters. For example: "Today, is the greatest day ever!" should return greatest because it has 2 e's (and 2 t's) and it comes before ever which also has 2 e's. If there are no words with repeating letters return -1. Words will be separated by single spaces.
