Dynamic Median Maintenance

In a theoretical city, you are responsible for maintaining a list of citizen heights as new citizens arrive continuously. Implement a program that reads from the input stream until EOF and tracks the median height after each arrival. The program should print the current median height after each new citizen's height is added. If the total number of heights is odd, the median is the middle height; if even, it is the average of the two middle heights rounded to two decimal places. Example: Input: 160 170 155 180 Output: 160.00 165.00 170.00 170.00
