Answer:
See explaination
Explanation:
Diverse Subset Problem is NP: When presented with a set of k customers, it can be checked in polynomial time that you wont at any time have two customers in the set have ever bought the same product.
Independent Set is known to be NP-complete.
Independent Set ?P Diverse Subset Problem: Suppose we have a black box for Diverse Subset Problem and want to solve an instance of Independent Set. For our Independent Set Problem, we have a graph G=(V,E) and a number k, and need to find out if G contains an independent set of size (at least) k. We need to reduce the Independent Set Problem to a Diverse Subset Problem. We do this by constructing an array where each v in V is a customer and each e in E is a product, and customer v purchased every product e for which the product edge e touches the customer node v. Then we ask the black box for the Diverse Subset Problem if there is a subset of k customers that is diverse.
The black box for the Diverse Subset Problem will return.
Answer:
Simplify a complex problem means reduces its complexity and make it easy to understand. When we make the problem simplified then, the data become more clear and understandable.
There are many ways to simplify a complex problem as follows:
- Organize the information and content properly and reduces the layers of complexity. Organized the content in the form of steps so that it become easy to understand.
- Use of clear language is one of the most important part to make the content more clear and use proper formatting of the data.
- Break the information into smaller parts to it can easy to read and looks more clearly. So, the reader finds it more comfortable and efficient.
DES is a commonly used symmetric encryption
A) is a commonly used symmetric encryption
<u>Explanation:</u>
DES stands for Data Encryption Standard. It is a symmetric key algorithm and is used for encrypting electronic data. It was developed in 1975. DES is one of the oldest encryption standards to be used in the industry.
The algorithm takes 16 rounds of permutations in order to encrypt data. But now, with the advent of technology, as new algorithms have been designed and put in use, DES is less preferable.
In the process of key generation, some keys generated sometimes turn out to be weak and hence are prone to attacks. If not for the weak keys generation, DES works perfectly fine and is an effective algorithm to encrypt data.
Answer:
look up the number (phone number) to call them and ask is they can cancel the account the debit card is abt to pay for :)
The answer would be B. $E$19 would keep the cell and row the same.
