Description Given m sequences, each contains n non-negative integer. Now we may select one number from each sequence to form a sequence with m integers. It's clear that we may get n ^ m this kind of sequences. Then we can calculate the sum of numbers…
It's well known that DNA Sequence is a sequence only contains A, C, T and G, and it's very useful to analyze a segment of DNA Sequence,For example, if a animal's DNA sequence contains segment ATC then it may mean that the animal may have a genetic di…
背单词,始终是复习英语的重要环节.在荒废了3年大学生涯后,Lele也终于要开始背单词了. 一天,Lele在某本单词书上看到了一个根据词根来背单词的方法.比如"ab",放在单词前一般表示"相反,变坏,离去"等. 于是Lele想,如果背了N个词根,那这些词根到底会不会在单词里出现呢.更确切的描述是:长度不超过L,只由小写字母组成的,至少包含一个词根的单词,一共可能有多少个呢?这里就不考虑单词是否有实际意义. 比如一共有2个词根 aa 和 ab ,则可能存在104个长度不…
