@Shaheer You didn’t specify which problem this code is for. I am assuming it is for problem A.

The issue here is with that loop.

The format specification says that there will be a number N in the first line. And then N numbers in the second line.

In Python, if you want to read N numbers all from one line, then instead of writing a loop like that, you need to do something like this:

line = input()
fields = line.split()
numbers = []
for x in fields:
   numbers.append(int(x))
# Now you have the numbers in `numbers` list

You can shorten this to:

numbers = map(int, input().split())

@Wasif_719 If you ask for the solution directly, you are going to miss out on the fun of actually solving the problem. :slight_smile:

Take a close look at the code given in the problem statement. It’s looping over the numbers 1 to N. For each number it is checking if the number is even or odd. If the number is even, it is adding the number to the variable sum. If the number is even, then it is adding twice of that number to the variable sum.

The goal here is to find the sum of all even numbers between 1 and N, and the sum of all odd numbers between 1 and N. And then, the result is SumOfEvenNumbers + 2 * SumOfOddNumbers.

@hjr265
The Problems of Mock 1 was added to Toph.
But it does not seem to be the case for Mock 2.
Will they be included in Toph?
