本题是leetcode121这道题的翻版,做法完全一样,也是扫一遍数组,维护两个值,一个是a[i]+i的最大值,另一个是a[i]+a[j]+i-j的最大值. class Solution: def maxScoreSightseeingPair(self, A: List[int]) -> int: best, ret = 0, 0 for i, v in enumerate(A): ret = max(ret, best + v - i) best = max(best, i + v) ret…

题目如下: Given an array A of positive integers, A[i]represents the value of the i-th sightseeing spot, and two sightseeing spots i and j have distance j - i between them. The score of a pair (i < j) of sightseeing spots is (A[i] + A[j] + i - j) : the su…

Given an array A of positive integers, A[i] represents the value of the i-th sightseeing spot, and two sightseeing spots i and j have distance j - i between them. The score of a pair (i < j) of sightseeing spots is (A[i] + A[j] + i - j) : the sum of…

Given an integer array, return the k-th smallest distance among all the pairs. The distance of a pair (A, B) is defined as the absolute difference between A and B. Example 1: Input: nums = [1,3,1] k = 1 Output: 0 Explanation: Here are all the pairs:…

You are given n pairs of numbers. In every pair, the first number is always smaller than the second number. Now, we define a pair (c, d) can follow another pair (a, b) if and only if b < c. Chain of pairs can be formed in this fashion. Given a set of…
