A milestone submission

This submission tells me that i have code for more than 10 days, with no
interrupt, continuously.
Data structure finished

The binomial heap doesn't complete, cause of the complexity.

Next, i will create a new folder to hold all the practice about data
stucture. I think the name is DataStruturePractice.

Next, i will practise the stl(standard template library).

Good luck for me.
