给定一个整数数组 A,对于每个整数 A[i],我们可以选择任意 x 满足 -K <= x <= K,并将 x 加到 A[i] 中. 在此过程之后,我们得到一些数组 B. 返回 B 的最大值和 B 的最小值之间可能存在的最小差值. 示例 1: 输入:A = [1], K = 0 输出:0 解释:B = [1] 示例 2: 输入:A = [0,10], K = 2 输出:6 解释:B = [2,8] 示例 3: 输入:A = [1,3,6], K = 3 输出:0 解释:B = [3,3,3] 或…

Given an array A of integers, for each integer A[i] we may choose any x with -K <= x <= K, and add x to A[i]. After this process, we have some array B. Return the smallest possible difference between the maximum value of B and the minimum value of B…

Given an array A of integers, for each integer A[i] we need to choose either x = -K or x = K, and add x to A[i] (only once). After this process, we have some array B. Return the smallest possible difference between the maximum value of B and the mini…

You have k lists of sorted integers in ascending order. Find the smallest range that includes at least one number from each of the k lists. We define the range [a,b] is smaller than range [c,d] if b-a < d-c or a < c if b-a == d-c. Example 1: Input:[…

LuoguP4234_最小差值生成树_LCT 题意: 给出一个无向图,求最大的边权减最小的边权最小的一棵生成树. 分析: 可以把边权从大到小排序,然后类似魔法森林那样插入. 如果两点不连通,直接连上,否则找到两点间最大的边权替换. 如果生成一棵树了就更新答案. LCT维护边权的最大值即可. 代码: // luogu-judger-enable-o2 #include <stdio.h> #include <string.h> #include <algorithm> u…
