    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;
     6 
     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.
