Remember, just the subproblem and recurrence structure (no code). You are a tourist visiting the planet Zondor and, since you are unfamiliar with Zondorian coins, you are burdened by way too many of them. The next time you buy something, you are determined to use as many of your coins as possible, and want to give the vendor exact change so you won’t receive any more coins as change.
For this problem, the Zondorian coins have integer values z1, z2, . . . , zn and you can assume that you have a limitless number of each coin. When you purchase something of value Y , you want to determine the maximum number of coins you can give to purchase the item with exact change (you may return some dummy value, -1, 0, ± [infinity], if it is not possible to exactly match Y ). For example, if (z1,z2,z3) = (3,7,11) and Y = 25, you could get rid of 3 coins (3, 11, 11) or, better, 7 coins (3, 3, 3, 3, 3, 3, 7).
So, the problem here is to perform the two steps to start the process of solving the MaxZondor- Coin problem.

Your task this week is to write a very simple spam classifier in python. it will classify messages as either spam (unwanted) or ham (wanted). the program will have a set of spam_words, words that are known to appear in spam messages. that set is included in the template file spam.pypreview the document. you will also define a spam threshold which reflects the allowed percentage of spam words in the message. you'll compute a 'spam indicator', which is the ratio of spam words to the total number of unique words in the message. if the spam indicator exceeds the spam threshold, the message is classified as spam. otherwise it is classified as ham. we'll assume that the spam threshold is a constant and has a value of 0.10. your program will prompt the user for a message and then will print the corresponding spam indicator with two decimal digits and the corresponding classification (spam or ham). the program will be case insensitive. the spam words are detected whether they are in lower case or upper case or mixed case. each word, spam or not, is counted once (even if it appears multiple times in the message.) the program will remove punctuation from the message before identifying the words and computing the spam indicator. for example '! ' must be identified as the spam word 'now'.
