Program Code package main import ( "fmt" ) // unionIntersection takes two slices of integers and returns their union and intersection. func unionIntersection(arr1, arr2 int) (int, int) { // Use…
Program Structure This Go program utilizes a recursive approach combined with a map (hash table) to identify duplicate subtrees in a binary tree. The key steps include: Defining the structure…
Program in Go package main import ( "fmt" "map" ) // Function to count distinct elements in every window of size k func countDistinct(arr int, k int) int { //…
Program Explanation This program counts the number of distinct elements in each window of size k in a given list of integers. It uses a sliding window approach combined with…
This program identifies duplicate subtrees in a binary tree using hashing. It utilizes a dictionary to keep track of serialized subtrees and their occurrences. Program Structure TreeNode Class: Defines the…
Program Overview This Python program demonstrates how to find the union and intersection of two arrays using hashing. Hashing allows for efficient membership testing, which is utilized to identify common…
Python Program def has_zero_sum_subarray(arr): """ Checks if there exists a subarray with a sum of zero. Parameters: arr (list of int): The input array to be checked. Returns: bool: True…
Python Program def longest_consecutive(nums): """ Find the length of the longest consecutive elements sequence in an array. Args: nums (List): A list of integers. Returns: int: The length of the…
Program def group_anagrams(strs): """ Groups anagrams from a list of strings. Parameters: strs (list): A list of strings to be grouped. Returns: list: A list of lists, where each sublist…
This program demonstrates how to find a contiguous subarray within a one-dimensional array of numbers that sums to a specified target value. We use a hashing technique for efficient lookup.…
