C/C++深层探索,网上下载的都没有书签阅读度起来非常不方便,这是我整理后的加上了书签,看起来就方便多了.(C/C++ Deeper exploration, have not downloaded bookmark degrees is very inconvenient to read, this is finished I added a bookmark, looks much more convenient.)

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.)

Matrix multiplication problem is a typical example of dynamical programming.
Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose.
For example, let A be a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix.
There are two different strategies to compute A*B*C, namely (A*B)*C and A*(B*C).
The first one takes 15000 elementary multiplications, but the second one only 3500.
Your job is to write a program that determines the number of elementary multiplications needed for a given evaluation strategy.
