Decadent weekly record

One week off, nothing to learn, nothing to read ......

Now, let's take a look at the mental retardation ideas we have made in this week, so that no mental retardation questions will be made at that time. ActuallySource codeIt is of little use to save it.CodeThere are a lot of searches on the Internet, and they won't be read by word during review. Although they are browsed in Wiz, they are rarely read.

Rqnoj:

331,343 is the most basic question of the Union Query

577 is a bit changed and the collection is checked, mainly because the enemy is a friend.

The maximum product of 311 is the classic interval motion gauge, which is a simple DP. It is divided by multiplication signs. f [I, X] = max (F [I, X], F [J, x-1] * s, data can not be high precision

40 web browsing can be classified as a linked list exercise. It is quite interesting, mainly because the content will not be saved after the browser retires and re-opens a new page, I used a nondescribable stack for simulation.

3jam notation to test the production of Arrangement

I used to simulate the 4 series, but I will repeat it. It is actually a carry-in system.

Usaco:

1.3 is a very mentally retarded question, but it has been done for a long time, stuck in 1.4.1

Friday is a simulation, but there are various simulation methods. It is said that there is another formula ......

Beads I 've been doing this for a long time, but it's also a variety of methods that can be seen as a piece of simulation. I think it's a bit like the largest subsequence and

Milk2 is a discretization method, and some people use the line segment tree

Transform seems to have appeared in the preliminary round. At first glance, it is very difficult, and it is also a simple simulation.

Namenum can be used to map dictionary words to numbers for direct comparison, that is, liner'sAlgorithm

The next two questions are related to the prime number of the background. The determination of the prime number and the hexadecimal conversion

Milk is part of a backpack and can be done with greed.

Barn1 is also a simple greedy

Crypt1 seems to have appeared in the preliminary round. Just simulate it.

Calfflac is also a simulation, but it has been tuned for a long time.

 

To sum up, the questions mentioned before usaco are very simple, but the quality is quite high. It is a good test and a good explanation, and there are fewer questions.
