Recursion is a programming technique where a function calls itself to solve smaller instances of the same problem, typically used to break down complex problems into simpler sub-problems.The Big PictureImagine you are looking at yourself in a series of mirrors that are facing each other. The image in each mirror reflects infinitely, getting smaller and smaller. Similarly, recursion involves a fu..

Merge sort is an efficient, stable, and comparison-based sorting algorithm that uses a divide-and-conquer approach to sort data by recursively splitting arrays and then merging the sorted sub-arrays.The Big PictureImagine you have a deck of cards that you want to sort. Merge sort is like dividing the deck into smaller piles, sorting each pile individually, and then merging the sorted piles back ..

Quick sort is an efficient sorting algorithm that uses a divide-and-conquer approach to organize data by partitioning arrays and recursively sorting the partitions.The Big PictureImagine you have a messy room full of books, and you want to organize them on a shelf. Quick sort is like picking a random book (called the "pivot"), then arranging all other books into two piles: those that should come..

Insertion sort is a simple and intuitive sorting algorithm that builds a sorted array (or list) one element at a time by comparing each new element to the already sorted elements and inserting it into its correct position.The Big PictureThink of sorting a hand of playing cards. You pick up the cards one by one and place each new card into the correct position relative to the cards already in you..

The Bellman-Ford Algorithm is used to find the shortest paths from a single source vertex to all other vertices in a weighted graph, even if some of the weights are negative.The Big PictureImagine you have a network of roads connecting various cities, with some roads having negative tolls (like discounts or cashbacks). The Bellman-Ford Algorithm helps you determine the shortest paths from your s..

Dijkstra's Algorithm is a method for finding the shortest path between nodes in a graph, akin to navigating the shortest route between cities on a map.The Big PictureImagine you have a map with various cities connected by roads. You want to find the shortest path from your home city to a destination city. Dijkstra's Algorithm helps you determine this shortest path by systematically exploring rou..

알고리즘과 자료구조의 기본 개념을 설명하고, 배열의 특징과 배열에서의 연산(읽기, 검색, 삽입, 삭제)에 대해 설명합니다.큰 그림알고리즘과 자료구조는 컴퓨터 과학에서 중요한 개념입니다. 알고리즘은 문제를 해결하기 위한 단계적 절차이고, 자료구조는 데이터를 효율적으로 관리하기 위한 구조입니다.핵심 개념알고리즘: 연산을 풀어나가는 절차자료구조: 목적에 맞게 데이터를 논리적으로 정리한 구조배열: 인덱스를 통해 접근할 수 있는 데이터의 집합세부 설명배열의 특징인덱스: 배열에서 데이터가 있는 위치를 가리키며, 0부터 시작합니다.연산 속도: 배열에서의 연산은 단계 수로 측정됩니다.배열에서의 연산A. 읽기특정 인덱스에 있는 값 확인: 컴퓨터 메모리 내의 주소를 통해 인덱스 위치의 값을 읽습니다.컴퓨터가 인덱스 3의 ..
