//Weekly challenge

//Bracket Matcher
//Have the function BracketMatcher(str) take the str parameter being passed
//and return 1 if the brackets are correctly matched and each one is accounted
//for. Otherwise return 0. For example: if str is "(hello (world))",
//then the output should be 1, but if str is "((hello (world))" the
//the output should be 0 because the brackets do not correctly match up.
//Only "(" and ")" will be used as brackets. If str contains no brackets
//return 1.

// 2. returns string "buzz" if divisible by 5,
