[Codility] Lesson 5 : CountDiv - JAVA 문제 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, .. 2022. 6. 17.
[Codility] Lesson 5 : PassingCars - JAVA 문제 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 traveling to .. 2022. 6. 15.
[Codility] Lesson 4 : MissingInteger - JAVA 문제 This is a demo task. Write a function: class Solution { public int solution(int[] A); } that, given an array A of N integers, returns the smallest positive integer (greater than 0) that does not occur in A. For example, given A = [1, 3, 6, 4, 1, 2], the function should return 5. Given A = [1, 2, 3], the function should return 4. Given A = [−1, −3], the function should return 1. Write an effic.. 2022. 6. 15.
[Codility] Lesson 4 : MaxCounters - JAVA 문제 You are given N counters, initially set to 0, and you have two possible operations on them: · increase(X) − counter X is increased by 1, · max counter − all counters are set to the maximum value of any counter. A non-empty array A of M integers is given. This array represents consecutive operations: · if A[K] = X, such that 1 ≤ X ≤ N, then operation K is increase(X), · if A[K] = N + 1 then op.. 2022. 6. 13.
[Codility] Lesson 4 : PermCheck - JAVA 문제 A non-empty array A consisting of N integers is given. A permutation is a sequence containing each element from 1 to N once, and only once. For example, array A such that: A[0] = 4 A[1] = 1 A[2] = 3 A[3] = 2 is a permutation, but array A such that: A[0] = 4 A[1] = 1 A[2] = 3 is not a permutation, because value 2 is missing. The goal is to check whether array A is a permutation. Write a functi.. 2022. 6. 11.
[Codility] Lesson 4 : FrogRiverOne - JAVA 문제 A small frog wants to get to the other side of a river. The frog is initially located on one bank of the river (position 0) and wants to get to the opposite bank (position X+1). Leaves fall from a tree onto the surface of the river. You are given an array A consisting of N integers representing the falling leaves. A[K] represents the position where one leaf falls at time K, measured in second.. 2022. 6. 8.
