Why I got ILE on a non-interactive problem?

I don't think I wrote abnormal code, so why I got ILE? ILE usually appears in interactive problems, so this is pretty strange.

    So what's the problem? Can you point this out? I couldn't find that anyway :(

      Probably because of your custom function for reading input.

        Not this problem. The real problem is the constant $$$T$$$.

        In FFT the result's size should be larger or equal to twice of the degree of the polynomial, which is $$$2t$$$. And it should be a power of $$$2$$$. So the size is $$$131072$$$, but I thought is was $$$65536$$$.

        Anyway, thank you for your advice.

Finally got accepted.

A lesson: There's a chance to get any verdict by less array size, except accepted.
