How can I eliminate any repeated elements in an array?

edit

One way to eliminate repeated elements in an array in Python is:

1. Convert the array to a set, which automatically eliminates duplicates.
2. Convert the set back to an array, if needed.

Here is an example:

arr = [1, 2, 3, 2, 4, 3, 5]
arr_set = set(arr)
arr = list(arr_set)
print(arr)

Output: [1, 2, 3, 4, 5]

Alternatively, you can use a loop to manually remove duplicates:

arr = [1, 2, 3, 2, 4, 3, 5]
new_arr = []
for elem in arr:
    if elem not in new_arr:
        new_arr.append(elem)
print(new_arr)

Output: [1, 2, 3, 4, 5]
