Problem 1383. Count letters occurence in text, specific to words with a given length.
Build a function with two input arguments: a string and a word length (number of letters), that outputs a vector of counts of the 26 letters of the alphabet, specific to words with a given length.
- Case insensitive.
- Words contain only letters a-zA-Z, but the string can contain punctuation.
Example
>> txt = 'Hello World, from MATLAB' ; >> nl = 5 ; % Number of letters. >> nlWords_getCounts(txt, nl) ans = 0 0 0 1 1 0 0 1 0 0 0 3 0 0 2 0 0 1 0 0 0 0 1 0 0 0
here, two 5 letters words are found: 'Hello' and 'World'. The output vector is the count of letters (1 to 26) in these two words taken together. For example, letter 12 is 'l/L' and we see that it appears 3 times, hence the count of 3.
