ABCheck.js

/* Using the JavaScript language, have the function ABCheck(str) take the str parameter being 
passed and return the string true if the characters a and b are separated by exactly 3 places 
anywhere in the string at least once (ie. "lane borrowed" would result in true because there 
is exactly three characters between a and b). Otherwise return the string false.  */
