**One Liner--Best Solution** \n\n**Approach/Logic:-**\n\n1- performing bitwise XOR operations on the input numbers and then applying some transformations to calculate the maximum sum.\n\n2- calculates the XOR of each number with the given integer \'k\', sorts the resulting list, and then groups the elements in pairs.\n\n3- For each pair, calculates the sum of the XOR results and filters out negative values.\n\n4- Finally, the function subtracts the sum of negative values from the total sum of the input list to get the maximum value.\n\n**Code->**\n```\nclass Solution:\n    def maximumValueSum(self, nums: List[int], k: int, edges: List[List[int]]) -> int:\n        return sum(nums) - sum(filter(lambda x: x < 0, map(sum, zip(sorted(map(lambda x: x - (x^k), nums))[::2], sorted(map(lambda x: x - (x^k), nums))[1::2]))))\n```\n**Time Complexity:-** **O(N)**\n**Space Complexity:-** **O(N)**\n\n**Code BreakDown->**\n\n=> sorted(map(lambda x: x - (x^k), nums)): Calculates the XOR of each element with k, sorts the results.\n\n=> [::2] and [1::2]: Slices the sorted list into even and odd indexed elements.\n\n=> map(sum, zip(...)): Calculates the sum of each pair of elements.\n\n=> filter(lambda x: x < 0, ...): Filters out negative values.\n\n=> sum(...): Calculates the sum of negative values.\n\n=> sum(nums) - sum(...): Calculates the maximum value sum.\n\n**Code Explaination->**\n\n=> The maximumValueSum function takes three arguments: nums (list of integers), k (integer), and edges (list of lists).\n\n=> The code calculates the maximum value sum using the following steps:-\n       > XOR each element of nums with k using (x^k) where x is each element of nums.\n       > Sort the resulting list of XOR results.\n       > Split the sorted list into two parts using slicing: even-indexed elements and odd-indexed elements.\n       > Calculate the sum of each pair of elements in the two lists.\n       > Filter out the negative sums using the filter function with a lambda function that checks if the value is less than 0.\n       > Subtract the sum of negative values from the total sum of nums using sum(nums) - sum(...).\n       > Return the final result, which is the maximum value sum.\n\n\nIf this explaination is impressive please give a like/vote...\n\n**JAI SHREE RAM**\n\n\n
