Codeforces Round #444 (Div. 2) D. Ratings and Reality Shows 贪心

http://codeforces.com/problemset/problem/887/D

题意：有一个模特，她有一个初始rating值 s。她每天可能进行拍照或show中的一种活动。每拍一次照，rating增加 a， 每参加一次show，rating减少 b。她现在想参加一次脱口秀。参加完脱口秀后的 l 天内， 她拍一次照rating增加 c，每参加一次show rating减少 d。要求参加脱口秀之前以及脱口秀之后 l 天内，她的rating是非负的。给出一些天数（从 0 开始）和当天的活动，求她应该选择哪一天参加脱口秀。如果有多解，输出其中最小的那个。

按照题目的意思来说要找最小的，那么我从1-n开始连续l个，看是否造成rating一直为非负数，如果成立则找到答案。不成立则处理当前的i，然后更新rating继续找。
