Image
 Here's the Python logic for finding all unique pairs in an array that sum up to a target value. Python Unique Pair Problem Write a Python function that finds all unique pairs in an array whose sum equals a target value. Avoid duplicates in the result. For example: Input: arr = [2, 4, 3, 5, 7, 8, 9] , target = 9 Output: [(2, 7), (4, 5)] Hints Use a set for tracking seen numbers. Check for complements efficiently. Example def find_unique_pairs(arr, target):     """     Finds all unique pairs in the array that sum up to the target value.     Parameters:     arr (list): The input array of integers.     target (int): The target sum value.     Returns:     list: A list of unique pairs that sum to the target value.     """     seen = set()     pairs = set()     for num in arr:         complement = target - num         if complement in seen:...

How to use Blockchain on Cloud

Blockchain applications are growing in the financial world. Security is the main motto behind blockchain applications. You cannot tamper a record once created.


How to use Blockchain on Cloud

What is a platform 

A platform is a place where you can develop applications.

Top Blockchain Cloud Platforms

The development needs to create a project and deploy it into production. So that the real use can feel by users at their end.

Ok...

Let us come to three popular cloud platforms that are highly used in Blockchain applications:
  1. HyperLedger
  2. IBM BlueMix
  3. Microsoft Azure

#1. HyperLedger

  • The Hyperledger project is led by Executive Director Brian Behlendorf, who has decades of experience dating back to the original Linux Foundation and Apache Foundation, as well as being a CTO of the World Economic Forum. So it's not surprising that Hyperledger has been well received. You can learn hyper Ledger here.

  • Many of the top business and industry leaders have joined the project, including Accenture, Cisco, Fujitsu Limited, IBM, Intel, J.P. Morgan, and Wells Fargo. It has also attracted many of the top blockchain organizations.

#2. IBM Bluemix

  • IBM is now offering blockchain technology that integrates with its traditional offerings, such as IBM Bluemix. Bluemix is an open-standards, cloud-based PaaS for building and managing applications.

  • IBM has integrated a blockchain stack from Hyperledger, which is part of the Lynx Foundation, and is establishing best practices in blockchain technology.

#3. Microsoft Azure


  • Ethereum is a Turing-complete blockchain framework for build applications. Microsoft aims to build more offerings based on blockchain technology and Hyperledger. It's also growing the Azure marketplace while transitioning to a portal for customers on Azure.

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...
