uva 11235 Frequent values(游程编码+区间最小值查询)


游程编码(Run Length Encoding , RLE)



用value[i] count[i] 分别表示 第i段的数值 和 出现次数;

num[p] left[p] right[p]分别表示位置p所在段的编号和左右端点的位置。




#include #include #include using namespace std; const int maxn = 100001; int n,q; int d[maxn][35]; int a[maxn]; int value[maxn],count_[maxn]; int num[maxn],left[maxn],right[maxn]; void RMQ_int(){ for(int i=0;i num[right_]-1) ans=max(ans,0); else{ ans=max(ans,RMQ(num[left_]+1,num[right_]-1)); } } printf("%d\n",ans); } } return 0; }
