XKC , the captain of the basketball team , is directing a train of nn team members. He makes all members stand in a row , and numbers them 1 cdots n1⋯n from left to right.
The ability of the ii-th person is w_iwi , and if there is a guy whose ability is not less than w_i mwi m stands on his right , he will become angry. It means that the jj-th person will make the ii-th person angry if j>ij>i and w_j ge w_i mwj≥wi m.
We define the anger of the ii-th person as the number of people between him and the person , who makes him angry and the distance from him is the longest in those people. If there is no one who makes him angry , his anger is -1−1 .
Please calculate the anger of every team member .
Input
The first line contains two integers nn and m(2leq nleq 5*10^5, 0leq m leq 10^9)m(2≤n≤5∗105,0≤m≤109) .
The following line contain nn integers w_1..w_n(0leq w_i leq 10^9)w1..wn(0≤wi≤109) .
Output
A row of nn integers separated by spaces , representing the anger of every member .
