Учитывая массив целых чисел, найдите сумму его элементов.

Примеры:

Input : arr[] = {1, 2, 3}
Output : 6
1 + 2 + 3 = 6

Input : arr[] = {15, 12, 13, 10}
Output : 50

# Python 3 code to find sum
# of elements in given array
def _sum(arr):
	
	# initialize a variable
	# to store the sum
	# while iterating through
	# the array later
	sum=0
	
	# iterate through the array
	# and add each element to the sum variable
	# one at a time
	for i in arr:
		sum = sum + i
		
	return(sum)

# driver function
arr=[]
# input values to list
arr = [12, 3, 4, 15]

# calculating length of array
n = len(arr)

ans = _sum(arr)

# display sum
print ('Sum of the array is ', ans)

# sum() is an inbuilt function in python that adds
# all the elements in list,set and tuples and returns
# the value
ans = sum(arr)

# display sum
print ('Sum of the array is ',ans)
