A Simple Solution is to sort the given array using a O(n log n) sorting algorithm like Merge Sort,Heap Sort, etc and return the element at index k-1 in the sorted array. Time Complexity of this solution is O(n log n). Java Arrays.sort() 1publicclassSolution{2publicintfindKthSmalle...
Partition the Array to Find the Kth Largest/Smallest Element The following is essentially similar to the nth_element algorithm. Each iteration, we pick a pivot element and then we partition the array into two halves, the one that has all elements smaller than it and the others that are large...
I was doing a problem in which we have to find kth smallest element using constant space and the array is read only. The array can be unsorted. Link to the problem :https://www.interviewbit.com/problems/kth-smallest-element-in-the-array/ I want to know how the binary search solution ...
Note: You may assume k is always valid, 1 ≤ k ≤ array's length. 都第几次多这样的题了,还是bug多得飞起 classSolution {public:intfindKthLargest(vector<int>& nums,intk) {intlen =nums.size();intstart =0;intend =len;//convert to kth smallest element sematick = len - k +1;while(...
