BlockChain C# Implementation, BlockChain by using c# What is proof-of-work? Proof-of-work is a mechanism that existed before the first blockchain was created. It's a simple technique that prevents abuse by requiring a certain amount of computing work. That amount of work is key to prevent spam and tampering. Spamming is no longer worth it if it requires a lot of computing power. Bitcoin implements proof-of-work by requiring that the hash of a block starts with a specific number of zero's. This is also called the difficulty. But hang on a minute! How can the hash of a block change? In case of Bitcoin a block contains details about a financial transaction. We sure don't want to mess with that data just to get a correct hash! To fix this problem, blockchains add a nonce value. This is a number that gets incremented until a good hash is found. And because you cannot predict the output of a hash function, you simply have to try a lot of combinations before you get a hash that satisfies the difficulty. Looking for a valid hash (to create a new block) is also called "mining" in the cryptoworld. In case of Bitcoin, the proof-of-work mechanism ensures that only 1 block can be added every 10 minutes. You can imagine spammers having a hard time to fool the network if they need so much compute power just to create a new block, let alone tamper with the entire chain. Implementing proof-of-work So how do you implement it? Let's start by modifying our block class and adding the nonce variable in it's constructor. I'll initialize it's value and set it 0.

https://github.com/leodeveloper/textmatching

INTRODUCTION Spend as much time as required to solve this problem. No time limit is applied. Write production quality code in your usual style, using C#. Do not use built-in language functionality to directly solve the problem. So do not use the built-in pattern matching functions: String::split(), String::indexOf(), String::lastIndexOf(), String::substring(), Regex.Match(), etc... The solution should provide this functionality if applicable. You may use the String class to hold information while your own algorithm does the matching. Do not copy an existing algorithm from the Internet; you do not need to implement the fastest possible algorithm. You may choose any means of accepting input and producing output, including the use of a test harness. Note: String functions not related to matching can be used. Please return the completed code in a zip file named CODE_TEST_<Candidate Name>.zip REQUIREMENTS Write an application that fulfils the following requirements: 1. Accepts two strings as input: one string is called "text" and the other is called "subtext" in this problem statement, 2. Matches the subtext against the text, outputting the character positions of the beginning of each match for the subtext within the text. 3. Allows multiple matches 4. Allows case insensitive matching ACCEPTANCE CRITERIA Input text: Polly put the kettle on, polly put the kettle on, polly put the kettle on we'll all have tea Subtext: Output: INTERCONTINENTAL EXCHANGE Code Test: Text Matching | v 1.00 © 2017 Intercontinental Exchange, Inc. Polly 1, 26, 51 Subtext: Output: polly 1, 26, 51 Subtext: Output: ll 3, 28, 53, 78, 82 Subtext: Output: Ll 3, 28, 53, 78, 82 Subtext: Output: X <no matches> Subtext: Output: Polx <no matches>

One of the most exciting features in the new version of Entity Framework (Entity Framework Core 1.0) is the addition of an in-memory data provider. This makes it possible to prototype applications and write tests without having to set up a local or external database. When you’re ready to switch to using a real database, you can simply swap in your actual provider. In this tutorial, I’ll show you how to set up the Entity Framework Core InMemory provider and use it to prototype a simple ASP.NET Core API

https://github.com/leodeveloper/twin-strings-problem

Twin-Strings-Problem Here is a solution provided to the twin strings problem. Problem Description Two strings, a and b, are said to be twins only if they can be made equivalent by performing some number of operations on one or both strings. There are two possible operations: SwapEven: Swap a character at an even-numbered index with a character at another even-numbered index. SwapOdd: Swap a character at an odd-numbered index with a character at another odd-numbered index. For example, a = "abcd" and b = "cdab" are twins because we can make them equivalent by performing operations. Alternatively, a = "abcd" and b = "bcda" are not twins (operations do not move characters between odd and even indices), and neither are a = "abc" and b = "ab" (no amount of operations will insert a 'c' into string b). Complete the twins function in the provided code. It has two parameters: An array of n strings named a. An array of n strings named b. The function must return an array of strings where each index i (0 ≤ i < n) contains the string Yes if ai and bi are twins or the string No if they are not. Input Format The provided code reads the following input from stdin and passes it to the function: The first line contains an integer, n, denoting the number of elements in a. Each line i of the n subsequent lines (where 0 ≤ i < n) contains a string describing ai. The next line contains an integer, n, denoting the number of elements in b. Each line i of the n subsequent lines (where 0 ≤ i < n) contains a string describing bi. Constraints 1 ≤ n ≤ 10^3 1 ≤ lengths of ai, bi ≤ 100 ai and bi are not guaranteed to have the same length. Strings ai and bi contain lowercase letters only (i.e., a through z). Output Format The function must return an array of strings where each index i (0 ≤ i < n) contains the string Yes if ai and bi are twins or the string No if they are not. Sample Input 0 2 cdab dcba 2 abcd abcd Sample Output 0 Yes No Explanation 0 Given a = ["cdab", "dcba"] and b = ["abcd", "abcd"], we process each element like so: a0 = "cdab" and b0 = "abcd": We store Yes in index 0 of the return array because a0 = "cdab" → "adcb" → "abcd" = b0. a1 = "dcba" and b1 = "abcd": We store No in index 1 of the return array because no amount of operations will move a character from an odd index to an even index, so the two strings will never be equal. We then return the array ["Yes", "No"] as our answer.
