You’re a construction engineer tasked with building a new transit center for a large city. the design for the center calls for a t-foot-long steel beam for integer t > 0. your supplier can provide you with an unlimited number of steel beams of integer lengths 0 < c1 < . . < ck feet. you can weld as many beams as you like together; if you weld together an a-foot beam and a b-foot beam you’ll have an (a + b)-foot beam. unfortunately, every weld increases the chance that the beam might break, so you want as few as possible. your task is to design an algorithm which outputs how many beams of each length you need to obtain a t-foot beam with the

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'.
