From 18:15 ~ 20:15 on 01.05 , I started the Virtual contest of 'Educational Codeforces Round 56 (Rated for Div. 2)' .

4 problems accepted ;

The biggest harvest I have was my gloomy heart on the fourth problem 'D. Beautiful Graph' ;

Submitting with 13 times and it accepted finally thanks to my friend CJH ;

OH , at last , I'm going to be crazy and blundered .

Saying it , I get the ans as soon as I had looked through the title and made it with the codes ; But the reality was that it got 'WA' or 'TLE' every times ;

It takes me more than 30 minutes on this problem . Perhaps it will never accepted until the end of the contest without CJH's help .

2 Tips :

Only getting the true ans can I then program it ;

Even if it is always not accepted I shouldn't make my heart blundering , I should always keep quiet and bright all the time ;

All right , keep going ;

Huuuua~~ I'm coming back , I'll fighting up ; The rest of HEOI are only 90 days , I haven't got any more time to think something else . all I need donging is just learning , learning and learning . Three Tips ： Learning the new knowledge ; Getting the contest dedicatedly ; Summarying always ;

Now go and go ;

For my first time had some attention on the codeforces, I just found the races on it which was very great,

I had a goal that I must take good grades on it , the succeeder never desert only a chance ;
