Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. Clarification: Confused why the returned value is an integer but your answer is an array? Note that the input array is passed in by refer.. 2021. 3. 7. [Codility] Lesson16 - Greedy algorithms: TieRopes Problem There are N ropes numbered from 0 to N − 1, whose lengths are given in an array A, lying on the floor in a line. For each I (0 ≤ I < N), the length of rope I on the line is A[I]. We say that two ropes I and I + 1 are adjacent. Two adjacent ropes can be tied together with a knot, and the length of the tied rope is the sum of lengths of both ropes. The resulting new rope can then be tied a.. 2021. 2. 25. [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] Lesson16 - Greedy algorithms: Max Nonoverlapping Segments Problem Located on a line are N segments, numbered from 0 to N − 1, whose positions are given in arrays A and B. For each I (0 ≤ I < N) the position of segment I is from A[I] to B[I] (inclusive). The segments are sorted by their ends, which means that B[K] ≤ B[K + 1] for K such that 0 ≤ K < N − 1. Two segments I and J, such that I ≠ J, are overlapping if they share at least one common point. In .. 2021. 2. 10. 이전 1 2 3 4 ··· 7 다음 728x90 반응형
