Formally, let M be the maximum and m the minimum value of ai for l ≤ i ≤ r; the range [l, r] is almost constant if M - m ≤ 1. Find the length of the longest almost constant range. Input The first line of the input contains a single integer n (2 ...
B. Approximating a Constant Range When Xellos was doing a practice course in university, he once had to measure the intensity of an effect that slowly approached equilibrium. A good way to determine the equilibrium intensity would be choosing a sufficiently large number of consecutive data points ...
The first line of the input contains two integersnandm(2 ≤ n ≤ 400, 0 ≤ m ≤ n(n - 1) / 2) — the number of towns and the number of railways respectively. Each of the nextmlines contains two integersuandv, denoting a railway between townsuandv(1...

题目:http://codeforces.com/contest/602/problem/B 题意 :给出一个含有 n 个数的区间,要求找出一个最大的连续子区间使得这个子区间的最大值和最小值的差值不超过 1 ,最后输出这个子区间的长度。 分析: 因为区间里面的数只能相差1,我就用fs与fx来表示这个
题目链接:http://codeforces.com/problemset/problem/602/B 题意: 给你一个相邻数差不超过 1 的序列,求最长子串的长度,满足子串中的最大值减最小值也不超过 1。 思路: 区间最大值,区间最小值分别用ST表去维护就可以了,然后之后去二分答案就好了 1 #include <iostream> 2 #include <cstdio> 3 #...
Find the length of the longest almost constant range. Input The first line of the input contains a single integer n (2 ≤ n ≤ 100 000) — the number of data points. The second line contains n integers a1, a2, …, an (1 ≤ ai ≤ 100 000). ...
