CountDiv Write a function: class Solution { public int solution(int A, int B, int K); } that, given three integers A, B and K, returns the number of integers within the range [A..B] that are divisible by K, i.e.: { i : A ≤ i ≤ B, i mod K = 0 } For example, for A = 6, B = 11 and K = 2, your function should return 3, because there are three numbers divisible by 2 within the range [6..11], namely 6..

PassingCars A non-empty array A consisting of N integers is given. The consecutive elements of array A represent consecutive cars on a road. Array A contains only 0s and/or 1s: 0 represents a car traveling east, 1 represents a car traveling west. The goal is to count passing cars. We say that a pair of cars (P, Q), where 0 ≤ P < Q < N, is passing when P is traveling to the east and Q is travelin..

1. Brackets Determine whether a given string of parentheses (multiple types) is properly nested. A string S consisting of N characters is considered to be properly nested if any of the following conditions is true: S is empty; S has the form "(U)" or "[U]" or "{U}" where U is a properly nested string; S has the form "VW" where V and W are properly nested strings. For example, the string "{[()()]..

Nesting A string S consisting of N characters is called properly nested if: S is empty; S has the form "(U)" where U is a properly nested string; S has the form "VW" where V and W are properly nested strings. For example, string "(()(())())" is properly nested but string "())" isn&apos;t. Write a function: class Solution { public int solution(String S); } that, given a string S consisting of N c..

Fish N voracious fish are moving along a river. Calculate how many fish are alive. You are given two non-empty arrays A and B consisting of N integers. Arrays A and B represent N voracious fish in a river, ordered downstream along the flow of the river. The fish are numbered from 0 to N − 1. If P and Q are two fish and P < Q, then fish P is initially upstream of fish Q. Initially, each fish has ..

함수형 프로그래밍 람다식 함수형 인터페이스 Collection vs Stream 중간 연산, 종료 연산 filter, distinct sorted map flatMap peek 메서드 참조 static method 참조 인스턴스의 인스턴스 메서드 참조 생성자 new 참조 클래스의 인스턴스 메서드 참조 array를 Stream으로 변환하기 1. 함수형 프로그래밍 입력을 넣을 경우 동일한 결과값을 리턴하는 함수와 같은 특징을 갖는 프로그램을 말합니다. 코드의 이해가 쉽고, 유지 보수 및 테스트가 쉽다는 장점이 있습니다. 함수형 프로그래밍의 핵심 개념은 일급 함수, 순수 함수, 고차 함수라는 특징입니다. 1.1. 일급 함수 함수를 값으로 다룰 수 있는 성질로, 변수에 담을 수 있습니다. 함수를 다른 함수의 매..
