Python Logic to Find All Unique Pairs in an Array
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:...
