This problem can be solved in a recursion. Suppose there are $n$books to lend out, and everyone can borrow one, then the following recursion: $$ \begin{aligned} N(n) &= N(n-1) + N(n-2) + N(n-3) \\ &= N(n-2) + N(n-3) + N(n-4) \\ &= N(n-4) + N(n-5) \\ &= 2N(n-5) \end{aligned} $$ where $N(n)$represents the number of plans to borrow $n$books from $n$books. For this question, if Xiao Ming has a new book worth $5$, he has to lend it out to A, B, and C. Each of the three students can borrow a book. Therefore, there are $N(5) = 2> times 2> times 3> times 3 = 36$ways to borrow it. Therefore, Xiao Ming had a total of $36$borrowing methods when he had $5$worth of new books.

If 14 students go to the teacher's house to borrow books, the teacher's study has four types of books: A, B, C, and D. Each student can borrow at most two books of different types. How many books can you borrow at least? Since each student can borrow at most two books of different categories, if all 14 students want to borrow books of the same category, the number of books they need to borrow must be the power of 2, which is: 14 × 16 × 25 × 31 × 38 × × 2^127 This was a very large number that required a special algorithm to calculate. However, if the books that 14 students want to borrow all belong to different categories, then the minimum number of books that need to be borrowed is the power of 2 minus 1, which is: 2^0 + 2^1 + 2^2 + + 2^127 - 1 Using mathematical induction, we can prove that this expression is a power of two, which is: 2^0 + 2^1 + 2^2 + + 2^127 = 2^128 Therefore, if all 14 students wanted to borrow books from different categories, they would need to borrow at least 2128 books.
