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...
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 integerttt(1≤t≤10...
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...

In one move you can choose an integeriii(1≤i≤n1 \leq i \leq n1≤i≤n), and addaia_iaitobib_ibior subtractaia_iaifrombib_ibi. What is the minimum number of moves needed to makebbbincreasing (that is, every element is strictly greater than every element before it)?
