2024年11月18日 · 我们发现可以插在前面一个前缀最大值 a j 的正后方，而 a j + 1 ∼ a i 是啥都固定了，并且 1 ∼ a j 是 f j。 还有一种情况是插在最前面。 那么得出 f i = ∑ j = 1 i − 1 f j + 1，则 f 1 = 1, f 2 = 2, f 3 = 1 + 2 + 1 = 4, f 4 = 1 + 2 + 4 + 1 = 8, ⋯, f k + 1 = 2 k。 因此设 f i, j 为前 i 位，现在 max 是 j 的答案即可。 为了方便，设 Q 0 = 0，最后答案是 f n, n 2。 const int N = 5e3 + 3; const ll mod = 998244353; const ll i2 = (mod+ 1)/ 2;
