Today we’re working with Linked Lists. Check out the Tutorial tab for learning materials and an instructional video!

A Node class is provided for you in the editor. A Node object has an integer data field, data, and a Node instance pointer, next, pointing to another node (i.e.: the next node in a list).

A Node insert function is also declared in your editor. It has two parameters: a pointer, head, pointing to the first node of a linked list, and an integer data value that must be added to the end of the list as a new Node object.

Today we’re discussing scope. Check out the Tutorial tab for learning materials and an instructional video!

The absolute difference between two integers, a and b, is written as |a - b|. The maximum absolute difference between two integers in a set of positive integers, elements, is the largest absolute difference between any two integers in elements.

The Difference class is started for you in the editor. It has a private integer array (elements) for storing N non-negative integers, and a public integer (maximumDifference) for storing the maximum absolute difference.

문제 설명

어떤 문장의 각 알파벳을 일정한 거리만큼 밀어서 다른 알파벳으로 바꾸는 암호화 방식을 시저 암호라고 합니다. 예를 들어 “AB”는 1만큼 밀면 “BC”가 되고, 3만큼 밀면 “DE”가 됩니다. “z”는 1만큼 밀면 “a”가 됩니다. 문자열 s와 거리 n을 입력받아 s를 n만큼 민 암호문을 만드는 함수, solution을 완성해 보세요.
