 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:...

Now that we’re in the swing of a new year, we’ve taken stock of the data analytics trends that are brewing and developed a list of the Top 5 trends we believe are going to dominate the industry this year. Even if some of them don’t realize their full potential in 2014, it promises to be an important year in which consumer trends and technology innovation will further shape a future in which companies make data-driven decisions.
1. Data Visualization Goes Mainstream
In the mid-90s, e-mail introduced the Internet to consumers, made it more accessible, and catalyzed user adoption. Similarly, data visualization will make data analytics more accessible in 2014. Visual analytics allows business users to ask interactive questions of their prepared data sets and get immediate visual responses, which makes the whole process engaging.
This trend will democratize access to data and foster a strong data analysis culture where business users will look for data and perform visual analysis before making decisions. The quick wins that data visualization provides will lead to a changed mindset that will allow for future forays into more advanced analytics that uses math, statistics, and complex data sets. In 2014, we could see some further innovation around collaboration of business users in answering business questions. Soon, the business utility and future of a dashboard could be determined by how many “likes,” “shares,” and comments it receives from business users.
