What is the minimum number of moves needed to make bb increasing (that is, every element is strictly greater than every element before it)? The first line contains a single integer nn (2≤n≤50002≤n≤5000). The second line contains nn integers, a1a1, a2a2, ..., anan (1≤ai≤1091...
CodeForces - 1437E Make It Increasing 线段树动态开点 https://codeforces.com/problemset/problem/1437/E 这是有限制的最长上升子序列 数字之间必须满足list[i] - list[j] >= i - j 处理的时候就是让list[i] - i,这样就得到了最长不下降子序列,非正数就赋成INF忽略不计,就可以算了,见到大佬门用upper...
Codeforces1437 E. Make It Increasing(LIS) 题意: 你有一个长度为n的数列a和一个含有k个不同整数的集合b,b中的数都在[1,n]内。 现在你可以进行一些操作,每次操作中你可以选择两个数i和x,并将x赋值给ai。其中1<=i<=n,但i不能出现在集合b中,而x可为任意整数。 求出将数列a变为严格上升序列的最小...
JUst Posting it for revision purpose. First solution, n adds and 1 mod First, let's make ai = x * n + i (for some x). Then, let's mod the whole array with n (making ai = i). If the "add update" changed one index, we can just add i + n - ...

it helps to ruins the experience for thousands of other coders — many of whom still seek the dreams that Bob once had. This is unfair and should not be tolerated. But we need to understand Bob's motivations if we want to create a meaningful solution, rather than just shouting "ban the...
For each test case, print a single number on a separate line — the minimum number of operations to perform on the sequence to make it strictly increasing. If a strictly increasing sequence cannot be obtained, print "-1". Input The first line of the input contains an integer tt (1≤t≤...
Codeforces Educational Codeforces Round 97 (Rated for Div. 2) E. Make It Increasing 题目链接 题解 在指定一些位置上的数不能更改的情况下需要将一个序列变为严格但调递增序列的所需要最少的修改次数 题解 首先判断掉不能修改的情况 不能修改的mm个位置将序列划分为m+1m+1个部分,显然这m+1m+1个部分...
