[FEATURE]: Searching & Sorting Algorithms

[New Feature] Searching and Sorting Algorithms

• Added reference implementations for searching (linear, binary) and sorting (bubble, quicksort, merge sort) algorithms.
• Useful for interview prep and algorithmic learning.

#[Sample] JS Algorithm (Binary Search):

function binarySearch(arr, target) { let left = 0, right = arr.length - 1; while (left <= right) { const mid = Math.floor((left + right) / 2); if (arr[mid] === target) return mid; if (arr[mid] < target) left = mid + 1; else right = mid - 1; } return -1; }
