+ Given the words in the magazine and the words in the ransom note, complete the checkMagazine function to return YES if he can replicate his ransom note exactly using whole words from the magazine; otherwise, return NO.
+ For example, the note is "Attack At Dawn". The magazine contains only "attack at dawn". The magazine has all the right words and even if there's a case mismatch, the answer is YES.
+ Another example, the note says "give two grand today" and the magazine contains "give me one grand today night". The magazine doesnt have all the right words, so the answer is NO.

+ A roman translator Brutus was hired by a merchant.
+ Brutus will be responsible for translating arabic numerals to roman and vise-versa
+ You need to help him and implement a couple of handy methods.
+ Roman numbers are represented by 7 different letters:
+
+ Symbol       Value
+ I             1
+ V             5
+ X             10

+ D             500
+ M             1000
+
+ For example, two is written as II in Roman numeral, just two one's added together. Twelve is written as, XII, which is simply X + II. The number twenty seven is written as XXVII, which is XX + V + II.
+
+ Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used:
+
+ I can be placed before V (5) and X (10) to make 4 and 9.
+ X can be placed before L (50) and C (100) to make 40 and 90.
+ C can be placed before D (500) and M (1000) to make 400 and 900.
