Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar Q. Given an array of equal-length strings, check if it is possible to rearrange the strings in such a way that after the rearrangement the strings at consecutive positions would differ by exactly one character. 주어진 같은 길이의 string 배열들에서, 한개의 char 씩만 교체 가능해서 연속적으로 이어지는 자리로 ..

Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar Q. Given a sorted array of integers a, find an integer x from a such that the value of abs(a[0] - x) + abs(a[1] - x) + ... + abs(a[a.length - 1] - x) is the smallest possible (here abs denotes the absolute value).If there are several possible answers, output the..

Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar Q. Consider integer numbers from 0 to n - 1 written down along the circle in such a way that the distance between any two neighboring numbers is equal (note that 0 and n - 1 are neighboring, too). Given n and firstNumber, find the number which is written in the radially oppos..
