The letters of the English alphabet A, B, C, .. . , Z are given ranks 1, 2, 3, ... , 26 respectively. Then they are coded as follows:
(i) A letter with rank 'n' is coded to the letter with rank r, where r is the remainder when 7n is divided by 26, here $$1 \leq r \leq 26$$.
(ii) For decoding reverse process is allowed.
Based on this coding process, answer the questions 56-60.
