So the idea is to replace each element of the given array by it's compressed value [index of this element if we sort the whole array]. It's simply done inO(n.log(n))n.log(n)). Also, save the inverse mapping, i.e.pos[compressedpos[compressedvalue(a[i])]=ivalue(a[i])]=i. ...
给定整数数组nums和整数k,请返回数组中第k个最大的元素。 请注意,你需要找的是数组排序后的第k个最大的元素,而不是第k个不同的元素。 你必须设计并实现时间复杂度为O(n)的算法解决此问题。 示例1: 输入:[3,2,1,5,6,4],k = 2输出:5
Given a sorted array, two integerskandx, find thekclosest elements toxin the array. The result should also be sorted in ascending order. If there is a tie, the smaller elements are always preferred. Example 1: Input: [1,2,3,4,5], k=4, x=3 ...
Define an array op define one priority queue q for initialize i := 0, when i < size of arr, update (increase i by 1), do − insert (arr[i, 0], {i, 0} )into q while q is not empty, do − current_element := top element of q delete element from q i := second elemen...

Thought of as a binary tree, a min-heap has the property that each node is less than or equal to its children. So, the root node is the minimum of a min-heap. Once we build a min-heap out of the array, we can pop its root to get the smallest element in it. Then, we ...
LWC 72: 786. K-th Smallest Prime Fraction Problem: A sorted list A contains 1, plus some number of primes. Then, for every p < q in the list, we consider the fraction p/q. What is the K-th smallest fraction considered? Return your answer as an array of ints, where answer[0] ...
