# Codeforces Round 887 E Ina of the Mountain(反悔贪心)
~~被这个题折磨了好久,决定写一篇题解~~ 先考虑没有这个$k$的限制的情况,等价于对原来的$a_i$序列的差分数组$b_i$,每次找到两个位置$1\le x 0$的位置进行$-1$的操作,后面对应的$+1$可以放在$b_ic[i]$,那么$c[i]$减去$k$对答案的贡献就是$0$,因为$d[i] ......

【题解】CF1852C Ina of the Mountain
我们先从题目的一部分入手。 如果说,我们没有当一个数为 $0$ 时,让这个数变成 $k$ 的性质,我们如何求答案呢? 很简单,在图上就是: 绿色线段的长度加起来即为答案(本图中是 $6$) 我们考虑很显然地,将一个数从 $0$ 变为 $k$ 即为将一个数一开始加上 $k$ 我们如果要让第 $i$ 列 ......
