I was solving a problem on HackerEarth which is as follows:
You are provided an array A of size N that contains non-negative integers. Your task is to determine whether the number that is formed by selecting the last digit of all the N numbers is divisible by 10. Print "Yes" if possible and "No" if not.
Here's what I did:
size = int(input())
integers = input()
integers = [i for i in integers.split(' ')]
last_digit = [i[-1] for i in integers]
number = int(''.join(last_digit))
if number % 10 == 0:
print("Yes")
else:
print("No")
The code seems correct to me, but the problem is that the online HackerEarth platform throws a runtime error NZEC, about which I have no idea. So, I want to know why(and what kind of) error occured here and what is the problem with my code.

Hackerearth says
For interpreted languages like Python, NZEC will usually mean
Usually means that your program has either crashed or raised an uncaught exception
Many runtime errors
Usage of an external library that is not used by the judge
For your case:
number = int(''.join(last_digit))
number is becoming a very very big number which is the reason you are getting NZEC error (they have limited memory and time to execute the problem)
size = int(input())
integers = input()
integers = [i for i in integers.split(' ')]
last_digit = [i[-1] for i in integers]
number = ''.join(last_digit) # keeping the number as string
if number[-1] == '0': # checking the last digit of the string to be 0
print("Yes")
else:
print("No")
