1, File class recursive exercise (statistics of the folder size)
- Requirement: 1, receive a folder path from the keyboard, statistics the folder size
2. File class Recursive exercise (delete this folder)
- Requirement: 2, receive a folder path from the keyboard, delete the folder
3. File class recursive exercise (copy)
- Requirements: 3, receive two folder path from the keyboard, copy one of the folders (contains content) to another folder
4. File class recursive exercise (print by level)
Needs: 4, from the keyboard to receive a folder path, the folder of all the files and the name of the folder to print at the level, for example: AAA is a folder, there are bbb.txt,ccc.txt,ddd.txt these files, such as the Eee folder, The Eee has fff.txt and ggg.txt, printing out tiers to AAA bbb.txt Ccc.txt Ddd.txt
eee fff.txt ggg.txt
5. Recursive exercises (Fibonacci series)
- No, Death bunny.
- The story starts in 1202, saying that there is an Italian youth named Fibonacci.
- In one of his writings he raises an interesting question: Suppose that a newborn bunny can grow into a big rabbit in one months, and a couple of rabbits in one months, and a couple of bunnies every month, and no death in a year,
- Q: How many pairs of rabbits do they breed in a year, a pair of newborn rabbits?
- 1 1 2 3 5 8 13
- The first month a pair of bunnies 1
- The second month a pair of big rabbits 1
- The third month a pair of big rabbits gave birth to a small rabbit 2
- The fourth month a pair of big rabbits gave birth to a pair of rabbits
- A couple of bunnies grow into big rabbits. 3
- Fifth month two to the big rabbit two pairs of rabbits
- A couple of bunnies grow into big rabbits. 5
6, recursive exercise (1000 of the factorial of all 0 and the number of trailing zeros)
- Requirements: Find the factorial of 1000 all 0 and the number of trailing zeros, do not have to do recursion
7, recursive exercise (1000 of the number of factorial tail zero)
- Requirement: Find out the number of 1000 factorial trailing zeros, and use recursion to do
