【题意】
每天掉一个盘子下来;盘子有大小从1..n依次增大n个盘子; 然后让你叠盘子; 最底层为n,倒数第二层为n-1….最上层为1; 让你输出每天叠了哪些盘子;【题解】
因为是要连续叠在一起的; 所以每一天其实都有一个固定要等待的盘子; 如果等到了那个盘子; 就一直往下走;输出连续的盘子; 没有的话,它就是下一个需要等待的盘子了; 【完整代码】#includeusing namespace std;#define lson l,m,rt<<1#define rson m+1,r,rt<<1|1#define LL long long#define rep1(i,a,b) for (int i = a;i <= b;i++)#define rep2(i,a,b) for (int i = a;i >= b;i--)#define mp make_pair#define ps push_back#define fi first#define se second#define rei(x) scanf("%d",&x)#define rel(x) scanf("%lld",&x)#define ref(x) scanf("%lf",&x)typedef pair pii;typedef pair pll;const int dx[9] = { 0,1,-1,0,0,-1,-1,1,1 };const int dy[9] = { 0,0,0,-1,1,-1,1,-1,1 };const double pi = acos(-1.0);const int N = 1e5+100;int n;int wait;int chuxian[N];int main(){ //freopen("D:\\rush.txt", "r", stdin); rei(n); wait = n; rep1(i,1,n) { int x; rei(x); chuxian[x] = 1; while (chuxian[wait]) { printf("%d ",wait); wait--; } puts(""); } //printf("\n%.2lf sec \n", (double)clock() / CLOCKS_PER_SEC); return 0;}
