Algorithms tag algorithms what will not ah
What binary heap? ?
qbxt time out of learning to speak, to do for some time before, but now she wrote on the blog
Maintenance three queues, the queue 1 indicates the beginning of the earthworms, queue 2 represents the cut each time separated by relatively long earthworms that part, each time the queue 3 represents a cut worms that are separated by a shorter part.
We first ordered sequence of the original, because no matter how cut, first cut the earthworm into two parts after a certain cut into more than two parts of a large earthworm
Looking for every cut which is only worms in the queue 1, queue 2, queue 3 of the first team to find an increased maximum length of earthworm count, then put him out of the team, the two parts were cut into the team 2, team 3 .
Finally merge output
Code:
#include <queue> #include <cstdio> #include <iostream> #include <algorithm> using namespace std; const int N = 10000010; unsigned long long n, m, q, u, v, a[N], ans[N], s, y, tot, t; queue<int>q1, q2, q3; int cmp (long x, long y) { return x > y; } int maxn () { long long x1 = -(1 << 30), x2 = x1, x3 = x1; if (!q1.empty ()) x1 = q1.front (); if (!q2.empty ()) x2 = q2.front (); if (!q3.empty ()) x3 = q3.front (); if (x1 >= x2 && x1 >= x3) {q1.pop (); return x1;} if (x2 >= x1 && x2 >= x3) {q2.pop (); return x2;} q3.pop ();return x3; } void putin (long long x1, long long x2) { if (x1 < x2) swap (x1, x2); q2.push(x1); q3.push(x2); return ; } int main () { scanf ("%lld%lld%lld%lld%lld%lld", &n, &m, &q, &u, &v, &t); for (long long i = 1; i <= n; i++) scanf ("%lld", &a[i]); sort (a + 1, a + 1 + n, cmp); for (long long i = 1; i <= n; i++) q1.push(a[i]); for (long long i = 1; i <= m; i++) { ans[i] = maxn() + y; long long j = ans[i] * u / v, k = ans[i] - j; y += q; putin (j - y, k - y); } while (!q1.empty () || !q2.empty () || !q3.empty ()) a[++tot] = maxn() + y; for (long long i = t; i <= m; i += t) printf ("%lld ", ans[i]); printf ("\n"); for (long long i = t; i <= tot; i += t) printf ("%lld ", a[i]); return 0; }
Thank you for watching, I wish good health!
