To move all the negative elements to one side of an array, you can use a two-pointer approach. The idea is to maintain two pointers: one pointing to the first element of the array and the other pointing to the last element of the array. The pointer at the front moves forward until it encounters … Read more

To find the kth minimum and maximum element in an array, you can first sort the array and then return the kth element. Here’s an example implementation in Kotlin: findKthMinMax takes an IntArray as input along with an integer k indicating which kth minimum and maximum elements to find, and returns a nullable Pair<Int, Int> … Read more
To find the minimum and maximum elements in an array, you can iterate over the array and keep track of the minimum and maximum elements you’ve seen so far. Here’s an example implementation in Kotlin. findMinMax takes an IntArray as input and returns a nullable Pair<Int, Int> containing the minimum and maximum elements. The function … Read more
To reverse an array, you can iterate over half of the array and swap each element with its corresponding element on the other end of the array. Here’s an example implementation in Kotlin : reverseArray takes an IntArray as input and returns an IntArray. The function first gets the length of the array n. The … Read more
To count the number of bits to be flipped to convert A to B using bit manipulation, you can perform the following steps: In this implementation, we define a function called countBitsToFlip that takes two integers a and b as input and returns the number of bits that need to be flipped to convert a … Read more
To find the median of a row-wise sorted matrix, we can follow the below steps: This function takes a 2D array matrix of integers as input and returns the median value as an integer. The function first finds the minimum and maximum elements in the matrix by iterating through all the rows. Then, it uses … Read more
To convert a min heap into a max heap, you can follow these steps: The minHeapToMaxHeap function takes an array of integers representing a min heap as input. It initializes the length of the array to n and calculates the index of the last non-leaf node in the heap as (n / 2) – 1. … Read more
To convert a Binary Search Tree (BST) into a Min Heap, you need to follow these steps: 1. TreeNode Class This class represents a node in a binary tree. It has three properties: value which stores the value of the node, left which points to the left child of the node, and right which points … Read more
A flattened binary search tree is a modified version of a binary search tree (BST) where all the nodes are arranged in a linear order. In a normal binary search tree, the left and right subtrees of each node are stored separately, which results in a tree-like structure. However, in a flattened binary search tree, … Read more
