Codility[Lesson 3] - Time Complexity(FrogJmp) A small frog wants to get to the other side of the road. The frog is currently located at position X and wants to get to a position greater than or equal to Y. The small frog always jumps a fixed distance, D. Count the minimal number of jumps that the small frog must perform to reach its target. Write a function: class Solution { public int solution(int X, int Y, int D); } that, given three inte.. 2021. 8. 26.

Codility[Lesson 2] - Arrays(CyclicRotation) An array A consisting of N integers is given. Rotation of the array means that each element is shifted right by one index, and the last element of the array is moved to the first place. For example, the rotation of array A = [3, 8, 9, 7, 6] is [6, 3, 8, 9, 7] (elements are shifted right by one index and 6 is moved to the first place). The goal is to rotate array A K times; that is, each element .. 2021. 8. 8.
