i gave round 805 today , and i realized i would be uploading a blog after each ( special to me ) contest where i ll try to write down all my honest realization .

in today's contest , i lacked implementation tactics , i was prepared with ideas for the first three question , but could not implement them on time . it took me around 1 hour to implement 2nd question and it is justified somewhere as i have solved way less problems so far , however the good thing is that i was able to focus till the end moment . and i am happy for my effort . i ll improve .. happy coding....
