Problem Description You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each node contains a single digit. Add the two numbers and return the sum as a linked list. You may assume the two numbers do not contain any leading zero, except the number 0 itself. Examples Example ...

Algorithm Fundamentals Core Data Structure Categories Data structures can be classified into several fundamental types: Linear Structures: Basic arrangements including arrays, linked lists, stacks, queues, and hash tables Tree Structures: Hierarchical organizations like binary trees and heaps Graph Structures: Complex networks representing man ...

Array Algorithms Binary Search Fundamentals Binary search operates on sorted sequences with distinct elements. The algorithm halves the search space repeatedly until locating the target or exhausting the range. Critical Implementation Details: Midpoint Calculation: Use mid = lo + (hi - lo) // 2 instead of (lo + hi) // 2 to prevent integer ove ...
