Hello everyone! Today, I encountered a very strange problem with question e1. I have one submission which is this: [link] And another submission which is this: [link] The only difference between the two is in line 123 and it's a very small difference, but the first one is accepted in 1800 seconds, and the second one in 6000 seconds. There is a huge difference. I wanted to know if anyone knows the reason for this big difference; it doesn't make any sense at all. That line executes about 100,000,000 times. I know it's a lot, but it doesn't make sense to me that this change would add 4 seconds to my code. I want to know if there could be another reason or if that's really all there is to it.
