But what about k? Find kth largest element in an array Sub-array A is greater than sub-array B if sum (A) > sum (B). Why does Queue have front but Priority-queue has top in stl? Find K closest Element by Sorting the Array: The simple idea is to sort the array.Then apply the method discussed to K closest values in a sorted array.. Find K closest Element using Heap: An efficient approach is to use a max heap data structure of size K.. Find the absolute difference of the array elements with X and push them in the heap. Process : The last element is 4. Finding Kth largest number in given array of large numbers All the elements in the array are distinct integers. Given an input stream arr [] of n integers. It may be assumed that 1 <= k <= n. If stream contains elements of non-primitive types, we may define our own compactor function and create a priority_queue accordingly. Rearrange an array in order - smallest, largest, 2nd smallest, 2nd largest, .. 6. Approach: A naive solution will be to sort the elements in the range and get the kth largest element, the time complexity of that solution will be nlog(n) for every query. Find the Kth largest element (not Kth largest unique element) after insertion of each element in the stream and if the Kth largest element doesn't exist, the answer will be -1 for that insertion. 2.

Job-a-Thon. Example 2: Input: N = 7, K Therefore,the given binary tree is a sum tree. Well, since we have considered a total number of k * factorial(n-1) permutations, we are left with k %= factorial(n-1), and that is going to be our new k for the next iteration. Given two integers N and K, find the Kth permutation sequence of numbers from 1 to N without using STL function.Note: Assume that the inputs are such that Kth permutation of N number is always possible. So, it may not follow the heap property. Use custom sorting to sort the array in non-decreasing order. Enhance the article with your expertise. Try to do it using constant extra space.
