poj 3941 Hideyuki is allowed by his father Ujisato some 1000 yen bills every month for his pocket money. In the first day of every month, the number of bills is decided as follows. Ujisato prepares n pieces of m-sided dice and declares the cutback k. Hideyuki rolls these dice. The number of bills given is the sum of the spots of the rolled dice decreased by the cutback. Fortunately to Hideyuki, Ujisato promises him to give at least one bill, even if the sum of the spots does not exceed the cutback. Each of the dice has spots of 1 through m inclusive on each side, and the probability of each side is the same. In this problem, you are asked to write a program that finds the expected value of the number of given bills.

在给定字符串中找出单词（ “单词”由小写字母字符大写字母和构成，其他非字母字符视为单词的间隔， 如、问空格号、数字等等；另外单个字母不算单词）；找到单词后，按照长度进行降序排序， （排序时如果长度相同，则按出现的顺序进行排列），然后输出到一个新的字符串中；如果某个单词重复出现多次， 则只输出一次；如果整个输入的字符串中没有找到单词，请输出空串。输出的单词之间使用一个“空格”隔开， 最后一个单词后不加空格。(Identify the word (" word" character from the uppercase and lowercase letters constituted, other non-alphabetic characters as word spacing, such as asking a space number, number, etc. another is not a single letter word) in a given string find words after descending order according to length, (if the same length, the order stated that appears when sorting arranged), and then output to a new string If a word is repeated several times, only output once If the entire input string is not found in word, outputs an empty string. Used between the output of a word " space" separated, no spaces after the last word.)
