要求重新排列一个由Red、White和Blue（这是荷兰国旗的颜色）构成的数组，使得所有的Red都排在最前面，White排在其次，Blue排在最后。

【输入格式】

一行多个字符串，每个字符串都是 "Red" "White" 或 "Blue"

【输出格式】

一行按要求将原来的多个字符串排序后输出。

【提示】

strtok()函数可从一个字符串中提取以特殊字符分隔的子串。

#include<cstring>

  char inStr[256];
  cin.getline(inStr,256);
  
  char* pch;
  pch = strtok (str," ,.-");
  while(pch != NULL)
  {
    cout << pch;
    pch = strtok (NULL," ,.-");
  }
