Problem Statement:
Here, we are given a list of numbers, we need to find and print the index of the number which has an equal sum of elements on its left and right. This means the sum of elements on the left side is equal to the sum of elements on the right side. If there is no such element exists, print “No such index exists”.
For example
Input
12 56 23 43 23 56 12
Output
3
Code for Sum of List Elements in Python:
l = input('Enter numbers list: ').split()
def check_sum_equality(l):
for i in range(1, len(l)):
if sum(l[0:i]) == sum(l[i+1:]):
return i
return 'No such index exists'
for i in range(len(l)):
l[i] = int(l[i])
print(check_sum_equality(l))Output:
