[USACO][2009][MAR][S] Look Up
Description
Farmer John's N (1 <= N <= 100,000) cows, conveniently numbered 1..N, are once again standing in a row. Cow i has height (1 <= <= 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 < . For each cow i, FJ would like to know the index of the first cow in line looked up to by cow i.
Format
Input
- Line 1: A single integer: N
- Lines 2..N+1: Line i+1 contains the single integer:
Output
- 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.
