## Overview

It takes me half year to finish the CLRS and learn a lot. This is my notes about the legendary book.

I have read the whole book and take the online MIT open Course. Thanks MIT for the online course.
I’ve also get resource from Chinese and English forum.

I want to share my note to other guy who is interested in the algorithm and thinking.
Please feel free to check it out. Hope it’s helpful to you. Thank you.

# 前言

## Overview

sum the primes from a to b, inclusive, a < b <= $10^{14}$.
Measure how long it takes your algorithm to sum the primes from 1 to $10^9$.
Determine the complexity of your algorithm and calculate how long it would take to sum for a=1, b = $10^{12}$.

## Algorithm

I have used the Sieve_of_Eratosthenes algorithm to delete the primes from the vector.

# 1.DHT Network

DHT(Distributed Hash Tables)is a class of a decentralized distributed system that provides a lookup service similar to a hash table; (key, value) pairs are stored in a DHT, and any participating node “Node (networking)”) can efficiently retrieve the value associated with a given key. Responsibility for maintaining the mapping from keys to values is distributed among the nodes, in such a way that a change in the set of participants causes a minimal amount of disruption. This allows a DHT to scale to extremely large numbers of nodes and to handle continual node arrivals, departures, and failures.

The key idea for the DHT network is utilize the pair(key,value) to store and retrieve the data in distributed system.

Hello,everyone,I am lin liu,come from China My major is computer science and I am studying in America now.

Soccer and Dota2 are my favorite sports.Besides that,I am also fond of studying the computer science technology ,especially the cloud computing and algorithm.

This blog will be updated in an indefinite schedule,including the technology passage,studying experience,life record and so on.The passage will be written in English,sometimes both in English and Chinese.Due to my poor English,maybe I will write some sentences you can’t understand.Please calm down,do not fuck me.I am learning. lol

Finally,thank you for your coming.Good luck,have fun~~
