[USACO09MAR]向右看齐Look Up

题目描述

Farmer John's N (1 <= N <= 100,000) cows, conveniently numbered 1..N, are once again standing in a row. Cow i has height H\_i (1 <= H\_i <= 1,000,000). Each cow is looking to her left toward those with higher index numbers. We say that cow i 'looks up' to cow j if i < j and H\_i < H\_j. For each cow i, FJ would like to know the index of the first cow in line looked up to by cow i. Note: about 50% of the test data will have N <= 1,000. 约翰的N(1≤N≤10^5)头奶牛站成一排,奶牛i的身高是Hi(l≤Hi≤1,000,000).现在,每只奶牛都在向右看齐.对于奶牛i,如果奶牛j满足i

输入输出格式

输入格式


\* Line 1: A single integer: N \* Lines 2..N+1: Line i+1 contains the single integer: H\_i 第 1 行输入 N,之后每行输入一个身高 H_i。

输出格式


\* Lines 1..N: Line i contains a single integer representing the smallest index of a cow up to which cow i looks. If no such cow exists, print 0. 共 N 行,按顺序每行输出一只奶牛的最近仰望对象,如果没有仰望对象,输出 0。

说明

FJ has six cows of heights 3, 2, 6, 1, 1, and 2. Cows 1 and 2 both look up to cow 3; cows 4 and 5 both look up to cow 6; and cows 3 and 6 do not look up to any cow. 【输入说明】6 头奶牛的身高分别为 3, 2, 6, 1, 1, 2. 【输出说明】奶牛#1,#2 仰望奶牛#3,奶牛#4,#5 仰望奶牛#6,奶牛#3 和#6 没有仰望对象。 【数据规模】 对于 20%的数据: 1≤N≤10; 对于 50%的数据: 1≤N≤1,000; 对于 100%的数据:1≤N≤100,000;1≤H_i≤1,000,000;
