Given an array of integers, find the sum of its elements.
Backup
Input : arr[] = {1, 2, 3}
Output : 6
1 + 2 + 3 = 6
Input : arr[] = {15, 12, 13, 10}
Output : 50
Solutie
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) Output:
Sum of the array is 34
