To rotate an array cyclically by one, you can perform the following steps: Here’s the Kotlin code to perform these steps: The rotateArrayByOne function is designed to rotate the elements of an integer array by one position in a cyclic manner. Here’s a detailed explanation of how the function works: main function first initializes an … Read more
To find the union of two sorted arrays, you can use a similar approach as finding the intersection of two sorted arrays. Here’s an algorithm to find the union of two sorted arrays: The time complexity of this algorithm is O(m + n), where m and n are the lengths of the two arrays. Here’s … Read more
To find the intersection of two sorted arrays, you can use the following algorithm: The time complexity of this algorithm is O(m + n), where m and n are the lengths of the two arrays. here’s an implementation of the algorithm in Kotlin: here are the steps involved in the intersection function in Kotlin:
The word break problem is a classic problem in computer science that involves breaking a given string into words using a dictionary. Given a string s and a dictionary of words, the goal of the word break problem is to determine whether s can be segmented into a space-separated sequence of one or more dictionary … Read more

To implement a phone dictionary using Trie, you would need to store a set of valid words in the Trie data structure, where each node represents a character in the words and edges connect parent nodes to their child nodes. Here’s an example implementation of a phone dictionary using Trie in Kotlin: In this example, … Read more
A Trie (pronounced “try”) is a tree-like data structure used to efficiently store and retrieve a large set of strings or sequences of characters. It is also known as a digital tree or prefix tree. In a Trie, each node represents a single character, and a path from the root node to any other node … Read more
To count the number of set bits (i.e., bits set to 1) in an integer, we can use bit manipulation. One approach is to use a loop to check each bit of the integer, starting with the least significant bit. We can do this by right-shifting the integer by 1 bit at a time and … Read more
To check whether a number is a power of 2 using bit manipulation, we can use the fact that a power of 2 has only one bit set in its binary representation. For example, 2 in binary is 10, 4 is 100, 8 is 1000, and so on. Therefore, if we subtract 1 from a … Read more
To find the median of two sorted arrays, we can use the divide and conquer strategy to divide the problem into smaller subproblems that can be solved recursively. Here’s a high-level algorithm to find the median of two sorted arrays nums1 and nums2: Here’s a Kotlin code that implements the above algorithm: Here’s a step-by-step … Read more
