728x90 문제풀이6 [Codility] Lesson15 - Caterpillar method: Abs Distinct Problem A non-empty array A consisting of N numbers is given. The array is sorted in non-decreasing order. The absolute distinct count of this array is the number of distinct absolute values among the elements of the array. For example, consider array A such that: A[0] = -5 A[1] = -3 A[2] = -1 A[3] = 0 A[4] = 3 A[5] = 6 The absolute distinct count of this array is 5, because there are 5 distinct.. 2021. 2. 15. [Codility] Lesson12 - Euclidean algorithm: Common Prime Divisors Problem A prime is a positive integer X that has exactly two distinct divisors: 1 and X. The first few prime integers are 2, 3, 5, 7, 11 and 13. A prime D is called a prime divisor of a positive integer P if there exists a positive integer K such that D * K = P. For example, 2 and 5 are prime divisors of 20. You are given two positive integers N and M. The goal is to check whether the sets of pr.. 2021. 2. 9. [Codility] Lesson8 - Leader : Dominator (c++) Problem An array A consisting of N integers is given. The dominator of array A is the value that occurs in more than half of the elements of A. For example, consider array A such that A[0] = 3 A[1] = 4 A[2] = 3 A[3] = 2 A[4] = 3 A[5] = -1 A[6] = 3 A[7] = 3 The dominator of A is 3 because it occurs in 5 out of 8 elements of A (namely in those with indices 0, 2, 4, 6 and 7) and 5 is more than a ha.. 2021. 1. 4. [Codility] Lesson6 - Sorting: Distinct Problem Write a function int solution(vector &A); that, given an array A consisting of N integers, returns the number of distinct values in array A. For example, given array A consisting of six elements such that: A[0] = 2 A[1] = 1 A[2] = 1 A[3] = 2 A[4] = 3 A[5] = 1 the function should return 3, because there are 3 distinct values appearing in array A, namely 1, 2 and 3.
