Problem 43169. Frequency Analysis of Text

Difficulty:
(39)
Rate

Frequency analysis is a common task in cryptoanalysis. It is essentially counting the occurrences of alphabets (regardless of case).

So for example,

s = 'This is a very good day'

frequency = [2 0 0 2 1 0 1 1 2 0 0 0 0 0 2 0 0 1 2 1 0 1 0 0 2 0]

Frequency is organized from a-z.

Please write a program that performs this calculation.
