Aracade Intro #33 stringsRearrangement. 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 ..
Aracade Intro #32 absoluteValuesSumMinimization. Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar
Aracade Intro #32 absoluteValuesSumMinimization. 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..

Aracade Intro #30 circleOfNumbers. 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..

Aracade Intro #29 chessBoardCellColor. Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar Q. Given two cells on the standard chess board, determine whether they have the same color or not. 체스판에서 주어진 두개의 셀이, 같은 색깔인지 아닌지 확인하라. e.g. For cell1 = "A1" and cell2 = "C3", the output should bechessBoardCellColor(cell1, cell2) = true. For cell1 = "A1" and cell2 = "H3", ..
Aracade Intro #28 alphabeticShift. Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar
Aracade Intro #28 alphabeticShift. Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar Q. Given a string, replace each its character by the next one in the English alphabet (z would be replaced by a). (Lowercase alphabet only) 주어진 문자열에서, 각 알파벳을 그 다음 알파벳으로 바꾸어라 ( a->b, c->d ) z 의 경우에는 다시 a 로 돌아간다. (전부 소문자 알파벳) e.g. Input -> inputString = "crazy" Output -> alphab..
Aracade Intro #27 variableName. Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar
Aracade Intro #27 variableName. Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar Q. Correct variable names consist only of English letters, digits and underscores and they can't start with a digit. Check if the given string is a correct variable name. 변수명으로 옳은 것은 알파벳, 숫자, 언더바로만 이루어져 있고, 시작은 숫자로 할 수 없다.옳은 변수명인지 확인하라. e.g. For name = "var_1__Int", the output s..
