1.PTA Experiment assignment （15 branch / topic ）
1.1 Electronic Wang
It is said that Wang Xingren's IQ can reach that of human beings 4 The level of a year old child , More intelligent Wang can do addition calculation . For example, you put two piles of balls on the ground , There were 1 A ball and 2 A ball , Smart Wang can use “ Wang ！ Wang ！ Wang ！” Express 1 Add 2 The result is 3.
You are required to do a simulation program for the electronic pet Wang , According to the number of two piles of balls recognized by the electronic eye , Work out and , And give the answer with Wang Xingren's call .

Find a good code , Understand code functions , And tell us what you can learn from the code you have chosen . Reference website ：
ACM Problem solving
leecode Interview several questions website .
subject
hold M Put the same apple on the N On the same plate , Some plates are allowed to remain empty , How many different methods are there ？（ use K Express ）5,1,1 and 1,5,1 It's the same division .
Code ：
The previous input is beyond my comprehension , But the meaning can still be understood in a general sense , He first set up a mathematical model for solving problems , Finally, it is realized by programming .
3. Learning summary （15 branch ）
3.1 Learning progress bar （5 branch ）
| Zhou / date | Time spent this week | Lines of code | Brief introduction of the knowledge learned | The confusing question at present |
|---|---|---|---|---|
| 10/12——10/18 | 20h | 157 | Simply copy the book and hit the code | |
| 10/19——10/26 | 35 | 481 | Learned if Statement and can understand the meaning of the code | |
| 10/27——11/8 | 67 | 832 | You've learned most of the cycle , Be able to understand the code and other functions that have been learned | The inability to use various sentences , It's very difficult to use nested statements |
3.2 Accumulate lines of code and blog words （5 branch ）
| Time | Blog words ( character ) | Lines of code |
|---|---|---|
| The first week | 1987 | 157 |
| In the second week of | 1532 | 481 |
| The third week | 4562 | 832 |
3.3 Learn to understand （5 branch ）
Sentiment ：1、 This week, the teacher as always did not talk about what content , But I learned to be more and more efficient , When I encounter problems, I like to ask others at the first time , I hope I can be better in the future .
2、 I don't study hard enough , There are a lot of good people around , I want to learn more from them , Otherwise, how can we stand out in the fierce competition in the future .
3、 Originally, I wanted three questions of the first big question to hang 15 points of the ladder of heaven , It turns out that I can't do it at all , There is still a lot to learn , come on. , Continue to work hard ！
