题目描述: Given an array of integers and an integer k, find out whether there are two distinct indices i and j in the array such that nums[i] = nums[j] and the absolute difference between i and j is at most k. Example 1: Input: [1,2,3,1], k = 3 Output: t…
There are two sorted arrays nums1 and nums2 of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). t int MAX = 0x7fffffff, MIN = 0x80000000; int kth(vector<int>& nums1, vec…
