Hello

My Name is Jose francisco

Write a program that counts the frequencies of each word in a text, and output each word with its count and line numbers where it appears.
We define a word as a contiguous sequence of non-white-space characters. Different capitaliz atio ns o f the same character sequence should be considered same word (e.g. Python and python).
The output is formatted as follows: each line begins with a number indicating the frequency of the word, a white space, then the word itself, and a list of line numbers containing this word.
You should output from the most frequent word to the least frequent. In case two words have the same frequency, the lexicographically smaller one comes first. All words are in lower case in the output.
