kth smallest element is the minimum possible n such that there are at least k elements in the array <= n. You are not allowed to modify the array ( The array is read only ).
How do you find the smallest KTH element?
Using Min-Heap
This is a good example of problem-solving via a heap data structure. The basic idea here is to create a min-heap of all n elements and then extract the minimum element K times. The last element to be extracted will be the Kth smallest element.
Which is the smallest element?
Thus, helium is the smallest element, and francium is the largest.

What is k th?
kth (not comparable) (mathematics) Occurring at position k in a sequence.
How do you find the largest KTH element?
If we sort the array in ascending order, the kth element of an array will be the kth smallest element. To find the kth largest element, we can pass k= length(Array) – k.
Where will the KTH minimum element found in a min heap?
The following steps are involved in finding the k t h k^{th} kth smallest element using a min-heap. Create a min-heap using the given array. Remove the element at the root of the heap k − 1 k-1 k−1 times. The element on the root of the heap is the k t h k^{th} kth smallest element.
What is the rarest element in the universe?
Astatine is the rarest naturally occurring element.
What is the lightest element on earth?
Hydrogen is the lightest element. Dihydrogen, H2, is a colorless, odorless, tasteless gas.
What is rarest element on earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
How do you find the largest and smallest number in an unsorted array?
1) Declare/provide input array 2) Initialize max and min numbers to some random numbers in array, let’s say inArray[0] 3) Traverse through the array 3.1) Check if the current element is greater than the max, if yes then set max to current element.
How do you find the kth smallest number in an array?
Using Min Heap
The idea is to construct a min-heap of size n and insert all the array elements A[0…n-1] into it. Then pop first k-1 elements from it. Now k’th smallest element will reside at the root of the min-heap.
How do you sort an array in C++?
First run: Enter total number of elements to read: 5 Enter element [1] 123 Enter element [2] 345 Enter element [3] 567 Enter element [4] 12 Enter element [5] 90 Unsorted Array elements: 123 345 567 12 90 Sorted (Ascending Order) Array elements: 12 90 123 345 567 Second run: Enter total number of elements to read: 120 …
What does KTH mean in statistics?
In statistics, the kth order statistic of a statistical sample is equal to its kth-smallest value. Together with rank statistics, order statistics are among the most fundamental tools in non-parametric statistics and inference.
How do you reverse an array in place in Java?
Reversing an array in java can be done in three simple methods. The first method is as follows: (i) Take input the size of array and the elements of array. (ii) Consider a function reverse which takes the parameters-the array(say arr) and the size of the array(say n).
How do you find the nth element of an array?
How to find the nth element in an array in Java
