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.…
The Two Sum problem is a classic algorithmic challenge where the goal is to find two numbers in an array that add up to a specific target sum. This implementation…
This Python program counts the frequencies of elements in an array using a hash table (dictionary). Hashing allows us to efficiently track the occurrences of each element in the array.…
Overview A hash table is a data structure that maps keys to values for efficient data retrieval. It uses a hash function to compute an index into an array of…
This document provides a simple implementation of a hash table in Java. A hash table is a data structure that offers a way to efficiently store and retrieve data using…
Java Program import java.util.HashMap; import java.util.Map; public class FrequencyCounter { /** * Counts the frequency of each element in the given array. * * @param array the array of integers…
