Problem 43169. Frequency Analysis of Text
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.
