WebYou can do it by FFT with some large two modulos, for example, modulo 1 + 7·226 and 1 + 5·225. Then you can restore the value using Chinese Remainder Theorem (or extended Euclidean algorithm). And finally modulo it by 109 + 7. Obviously, this way also works for 109 + 9, 998244353, or some other modulos. WebJan 29, 2024 · Formulation. Let m = m 1 ⋅ m 2 ⋯ m k , where m i are pairwise coprime. In addition to m i , we are also given a system of congruences. { a ≡ a 1 ( mod m 1) a ≡ a 2 … WebThere must exist a pair of integers x1 and x2 such that both of them have the same remainders after dividing by any ci, but they differ in remainders after dividing by k. Find more facts about x1 and x2! Solution Consider the x1 and x2 from the hint part. We have x1 - x2 ≡ 0 () for each 1 ≤ i ≤ n. So: We also have ( ). As a result: csr sticker
