In a certain code the m“letter of the English alphabet is coded as the $$n^{th}$$ letter where n is the remainder obtained when 7m + 5 is divided by 26, $$1 \leq n \leq 26$$. For example, the third letter C becomes $$(7 \times 3 + 5) = 26^{th}$$ letter Z in the coded language. For decoding, the reverse process is followed. Based on this information, answer the questions.
Based upon the following coding system and ihe conditions (i), (ii), (iii), given below answer the questions.
Conditions:
(i) If the first element is a symbol and the last element is a number, then the codes for both elements are to be interchanged
(ii) If both the first and the last elements are symbols, then the last element's code is to be taken as the code for the first element.
(iii) If the group of elements contain ony one symbol, then that symbol is to be coded as A.
