Description Can you solve this? What two positive numbers can make this possible: n1 > n1 + n2 OR n2 > n1+ n2

Note: This challenge launches an instance on demand.

The program asks us to provide 2 integers that would satisfy the equation:

n1 > n1 + n2 OR n2 > n1 + n2

we will not exit the program (unlike the first one) and in order to finally get the flag we need to ensure that num1 > 0 || num2 > 0.

We can overflow the sum with 2 positive integers to satisfy all the conditions, so entering: 1073741824, 1073741824 we can get the flag:
