문제 설명: Given an array of bird sightings where every element represents a bird type id, determine the id of the most frequently sighted type. If more than 1 type has been spotted that maximum amount, return the smallest of their ids. Example arr = [1, 1, 2, 2, 3] There are two each of types 1 and 2, and one sighting of type 3. Pick the lower of the two types seen twice: type 1. Function Descripti..

문제 설명: Given an array of integers and a positive integer k, determine the number of [i, j] pairs where i < j and ar[i] + ar[j] is divisible by k. Example ar = [1, 2, 3, 4, 5, 6] k = 5 Three pairs meet the criteria: [1, 4], [2, 3] and [4, 6]. Function Description Complete the divisibleSumPairs function in the editor below. divisibleSumPairs has the following parameter(s): int n: the length of arr..

문제 설명: Maria plays college basketball and wants to go pro. Each season she maintains a record of her play. She tabulates the number of times she breaks her season record for most points and least points in a game. Points scored in the first game establish her record for the season, and she begins counting from there. Example scores = [12, 24, 10, 24] Scores are in the same order as the games pla..

Determine all integers that satisfy the following two conditions: The elements of the first array are all factors of the integer being considered The integer being considered is a factor of all elements of the second array These numbers are referred to as being between the two arrays. Determine how many such numbers exist. Example a = [2, 6] b = [24, ..

UIView 화면의 콘텐츠를 표시하고 관리를 담당하는 사각형의 영역을 가진 객체를 UIView라고 정의한다. UIButton, UILabel등의 화면 구성요소들 또한 모두 UIView라고 지칭하며, 해당 객체를 관리하기 위해 존재하는 객체를 UIViewController라고 한다. UIViewController의 기능 View의 컨텐츠를 업데이트 하고, View와 사용자간에 상호작용에 반응하는 역할을 한다. 또한 인터페이스의 레이아웃을 관리 및 View의 사이즈를 조정하는 역할 뿐만 아니라, 다른 컨트롤러를 통한 화면 전환 기능 또한 수행한다.
