(Codility) CountNonDivisible - Javascript 문제 You are given an array A consisting of N integers. For each number A[i] such that 0 ≤ i < N, we want to count the number of elements of the array that are not the divisors of A[i]. We say that these elements are non-divisors. For example, consider integer N = 5 and array A such that: A[0] = 3 A[1] = 1 A[2] = 2 A[3] = 3 A[4] = 6 For the following elements: A[0] = 3, the non-divisors are: 2, 6,.. 2021. 7. 18.
(Codility) MinPerimeterRectangle - Javascript 문제 An integer N is given, representing the area of some rectangle. The area of a rectangle whose sides are of length A and B is A * B, and the perimeter is 2 * (A + B). The goal is to find the minimal perimeter of any rectangle whose area equals N. The sides of this rectangle should be only integers. For example, given integer N = 30, rectangles of area 30 are: (1, 30), with a perimeter of 62, (.. 2021. 7. 17.
(Coldility) EquiLeader - Javascript 문제 A non-empty array A consisting of N integers is given. The leader of this array is the value that occurs in more than half of the elements of A. An equi leader is an index S such that 0 ≤ S < N − 1 and two sequences A[0], A[1], ..., A[S] and A[S + 1], A[S + 2], ..., A[N − 1] have leaders of the same value. For example, given array A such that: A[0] = 4 A[1] = 3 A[2] = 4 A[3] = 4 A[4] = 4 A[5].. 2021. 7. 16.
(Codility) Stone Wall - Javascript 문제 You are going to build a stone wall. The wall should be straight and N meters long, and its thickness should be constant; however, it should have different heights in different places. The height of the wall is specified by an array H of N positive integers. H[I] is the height of the wall from I to I+1 meters to the right of its left end. In particular, H[0] is the height of the wall's left e.. 2021. 7. 16.
