Array addition will always return False

[Gazzar14]

''''

Have the function ArrayAdditionI(arr) take the array of numbers stored in arr
and return the string true if any combination of numbers in the array can be
added up to equal the largest number in the array, otherwise return the string
false. For example: if arr contains [4, 6, 23, 10, 1, 3] the output should
return true because 4 + 6 + 10 + 3 = 23. The array will not be empty, will not
contain all the same elements, and may contain negative numbers.

Examples:

Input: [5, 7, 16, 1, 2]
Output: false

Input: [3, 5, -1, 8, 12]
Output: true

'''

def ArrayAdditionI(arr):
arr = sorted(arr)
maximum = arr[-1]
arr = arr[:1]
total = 0

for i in range(len(arr)):

	total = total + arr[i]
	if total == maximum:
		return 'true'
	
	for j in range(len(arr)):
		if j != i:
			total = total + arr[j]
			if total == maximum:
				return 'true'
	
	for k in range(len(arr)):
		if k != i:
			total = total + arr[k]
			if total == maximum:
				return 'true'
	
	return 'false'

print(ArrayAdditionI([3, 5, -1, 8, 12]))

Thanks for pointing this out!
