Minimum and maximum summation from array

Question

I want to print the minimum sum and the maximum sum of 4 of 5 elements for my array. When I check my result step by step it seems right, though for main result my answer is false.

def miniMaxSum(arr):
    minimum = 10**9
    maximum = 0
    for i in arr:
        newArray = arr
        newArray.remove(i)
        sumArray = 0

        for e in newArray:
            sumArray += e

    if sumArray < minimum:
        minimum = sumArray
    if sumArray > maximum:
        maximum = sumArray
    
return minimum, maximum

myArr = [1,2,3,4,5]

Output: (6, 14)

Has to be (10, 14).

`newArray` and `arr` are pointing to the same list. You need to make a copy like in the linked question. — Wups, Oct 28 '20 at 12:16
Do you _always_ want the sum of minimum or maximum `k` out of `k+1` elements? If so, you could just do `min_sum = sum(arr) - max(arr)` and analogously for `max_sum` — tobias_k, Oct 28 '20 at 12:18
yes always k out of k+1 elements and copying the array is fixed my problem — ExDet, Oct 28 '20 at 12:19

def miniMaxSum(arr):
    arr = sorted(arr)
    minimum = sum(arr[:-1])
    maximum = sum(arr[1:])

    return minimum, maximum

If your goal is to get the min and max sum of all elements except one you can just do this.

yes but my array can change like arr = [2,5,3,1,4] – ExDet Oct 28 '20 at 12:15

that's why you have to sort – JLeno46 Oct 28 '20 at 12:16
ok that is useful but i also want to learn what makes my code false. – ExDet Oct 28 '20 at 12:17
If knowledge is what you seek, I suggest this: https://docs.python.org/3/library/copy.html – JLeno46 Oct 28 '20 at 12:24
