In this post, we will solve the Caesar Cipher HackerRank Solution. This problem (Caesar Cipher) is a part of the HackerRank Problem Solving series.
Julius Caesar protected his confidential information by encrypting it using a cipher. Caesar’s cipher shifts each letter by a number of letters. If the shift takes you past the end of the alphabet, just rotate back to the front of the alphabet. In the case of a rotation by 3, w, x, y and z would map to z, a, b and c.
Original alphabet: abcdefghijklmnopqrstuvwxyz Alphabet rotated +3: defghijklmnopqrstuvwxyzabc
