Mar 28, 2025 · Write a Python program that removes all duplicate elements from an array and returns a new array. Sample Solution-1: return sorted(set(nums),key=nums.index) print(array_num[i], end=' ') print(result[i], end=' ') print(array_num[i], end=' ') print(result[i], end=' ') Sample Solution-2: return list(collections.OrderedDict.fromkeys(nums))

Dec 27, 2024 · Learn how to remove duplicates from an array (or list) in Python using methods like set(), list comprehensions, and pandas. Step-by-step examples for clean.

Mar 22, 2022 · for i in range(len(array)): for j in array: if array[i] == j: and then some operation to remove the element from the array. However, this will just remove every instance of every duplicated element.

Jul 28, 2010 · A better solution is sort the array and then check each element to the one next to it to find duplicates. Choose an efficient sort and this is O(n log n). The disadvantage with the sort-based solution is order is not maintained.
