Wrong name for main class, you cannot just name it class Main, name it class Codechef.

That’s not the issue tho. But I did it as u said. Showing the same error.

This problem only arises when you try only running the code without any custom input, whereas if you would try running your cone on some custom input or directly submitting the code the error might not show.

And you are taking input in the array the wrong way. You are overriding the first array element everytime you take an array element input because of the while loop. The while loop is totally unnecessary here.
