[USACO09MAR] Look Up S

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 $N(1\le N\le10^5)$ 头奶牛站成一排,奶牛 $i$ 的身高是 $H_i(1\le H_i\le10^6)$。现在,每只奶牛都在向右看齐。对于奶牛 $i$,如果奶牛 $j$ 满足 $i<j$ 且 $H_i<H_j$,我们可以说奶牛 $i$ 可以仰望奶牛 $j$。 求出每只奶牛离她最近的仰望对象。 Input

输入输出格式

输入格式


1. \* 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:$1\le N\le10$; 对于 $50\%$ 的数据:$1\le N\le10^3$; 对于 $100\%$ 的数据:$1\le N\le10^5,1\le H_i\le10^6$。
