Write two functions 'encryption' and 'decryption' that encrypt and decrypt the input string (any text), respectively. The characters must be encrypted as follows:
'a' -> 1,
'b' -> 2,
...,
i -> 9,
j - > 10#,
k -> 11#,
...,
z -> 26#
encryption('hello') ----> '8512#12#15#'
decryption(encryption('hello')) ----> decryption('8512#12#15#') ----> 'hello
Write a Python function by the name 'consecutiveSequence' that takes two arrays (or lists) as inputs and returns 'True' if the elements of the combined array is in a consecutive sequence.
consecutiveSequence([7, 4, 5, 1], [2, 3, 6]) ---- > True
consecutiveSequence([11, 14, 16, 15], [12, 17, 18, 19]) ---- > False
consecutiveSequence([34, 36], [35]) ---- > True
consecutiveSequence([1, 4, 5, 6], [2, 3, 7, 8, 10]) ---- > False
