Q1

input:A row of figures separated by commas

output:A row of figures separated by commas according to the original order.Each number=the original value*the nth time appeared

My answer：

 1 #include<iostream>

 2 #include<string>

 3 #include<array>

 4 #include<cmath>

 5 using namespace std;

 7 

 8 int main(){

 9 

10     //输入获取 每个输入字符存入字符串inputString

11     string inputString;

12     cin>>inputString;

13     int stringLen=inputString.length();

14     

15     //剔除逗号，逗号之间的数存入数组numArray的每个元素里

16     int *numArray=new int[100]();

17     int numArrayLen=0;

18     

19     int i=inputString.find(",");

20     for(int j=0,jj=i-1;j<i,jj>=0;j++,jj--){

21     numArray[0]+=(inputString[j]-48)*pow(10.0,jj);

22     }

23 

24     inputString[i]=' ';

25     int ii=inputString.find(",");

26     

27     while(ii!=string::npos){

28         numArrayLen++;

29     for(int j=i+1,jj=ii-i-2;j<ii,jj>=0;j++,jj--){

30         numArray[numArrayLen]+=(inputString[j]-48)*pow(10.0,jj);

31     }

32     i=ii;

33     inputString[ii]=' ';

34     ii=inputString.find(",");

35     }

36     

37     numArrayLen++;

38     for(int j=i+1,jj=stringLen-i-2;j<stringLen,jj>=0;j++,jj--){

39     numArray[numArrayLen]+=(inputString[j]-48)*pow(10.0,jj);

40     }

41     

42     //计算每个数的出现次数,并更新数组

43     int *numCount=new int[1000]();

44     for(int j=0;j<=numArrayLen;j++){

45         numCount[numArray[j]]++;

46         numArray[j]*=numCount[numArray[j]];

47     }

48 

49     //按照要求的格式输出

50       for(int j=0;j<numArrayLen;j++)cout<<numArray[j]<<",";

51       cout<<numArray[numArrayLen];

52       

53 }

I did not realize my knowledge was so weak until the test.There are a lot of c++ function that I did not know before or didn't know how to use it well.Consequently,I must still keep fighting harder.By the way ,coding them strengthens my debug aility.F10~~

 

Ps:It is my first time to write something here in English.

On one hand ,to record a noob who hope to grow into a female geeker on programming.On the other hand,to train my English writing.

Please enlighten.
