Algorithm and Array Helper Functions for npm

This npm package offers a collection of algorithm utilities and array helper functions, including search algorithms, mathematical operations, and array transformations.

📦 Installation

npm install algorithm-helpers

🚀 Usage

const algo = require('algorithm-helpers');

🔍 Search Algorithms

binarySearch(arr, target): Finds an element in a sorted array.

linearSearch(arr, target): Finds an element in an unsorted array.

🧮 Math Operations

factorial(n): Computes the factorial of a number.

fibonacci(n): Returns the nth Fibonacci number.

sum(arr): Calculates the sum of array elements.

average(arr): Computes the average of array elements.

max(arr): Finds the maximum value in an array.

min(arr): Finds the minimum value in an array.

🧹 Array Operations

unique(arr): Removes duplicates from an array.

flatten(arr): Flattens nested arrays into a single array.

chunk(arr, size): Splits an array into sub-arrays of specified size.

groupBy(arr, key): Groups objects in an array by a specified property.

difference(arr1, arr2): Finds elements in the first array not present in the second.

intersection(arr1, arr2): Finds common elements between two arrays.

reverseString(str): Reverses a given string.

🧪 Example Usage

console.log(algo.binarySearch([1, 2, 3, 4, 5], 4)); // 3 console.log(algo.linearSearch([10, 20, 30], 20)); // 1 console.log(algo.factorial(5)); // 120 console.log(algo.fibonacci(7)); // 13 console.log(algo.sum([1, 2, 3])); // 6 console.log(algo.unique([1, 2, 2, 3])); // [1, 2, 3] console.log(algo.chunk([1,2,3,4,5], 2)); // [[1,2],[3,4],[5]]
