What is the experience of brushing 500 water questions?

And there's no egg to use.

I immediately sophomore, the freshman two semester visually cut 1000 water problems, meaningless.

The KMP and suffix arrays are not understood so far, only templates.
What is number theory and game theory? Can you eat it? Only the table will be played.
Graph theory so far does not Tarjan, say DLX is what?
Plug DP, what is this?
The data structure is good, often do high school students, can be persisted in the persistence of the line tree can also spend an afternoon to write, but does not exam.

Usually do the problem only brush water, when encountering problems, and then search the problem, looked at, wow, this incredibly can do! Then copy the others code, hand it over to AC.

CF has almost no shortage in a year, it took a big first half time to roll on the div1. But so far the purple is a bunch, the yellow name one did not. Later do CF, often open the trumpet dozen div2, take a top 50 ranking, complacent.

TC fell to 700 in the freshman, then did not want to fight again.

The campus ACM Team recruit New, I thought I should still be a more serious person. I took a look at the students who came into contact with ACM, the first CF was Purple, then I felt that I was a freshman in the dog ate.

Do all sorts of mess company's competition, barely in the first 1000, get a piece of clothing.

I think I spent a lot of time on the ACM above, the whole freshman in addition to playing the game is ACM, skipping lessons countless. The grade in the class did not hang, but also did not have a door above 80 points, feel oneself quickly scrap.

I think my IQ is not suitable for playing ACM, ambitious, water dying, the bones are waves, fear of failure.

Originally wanted to be anonymous, think about it or forget it.

Serious Pure spit groove to: Cut 500 water problem, still better take small petition seriously really look over.

Ashamed of my seniors, and the exception let me into the summer camp training coach.

End.
