Define a function named build_dictionary(words_list) that takes a list of words as a parameter. The function creates a dictionary by looping through each element in the list and creating a corresponding key: value item.
The keys consist of integers and the values are lists of unique words in lowercase where the length of each word equals the key value.
Notes
• You can assume there will be no punctuation characters in the words in the parameter words_list (i.e., only letters). However, you should convert all words to lower case.
• You can assume that the file only contains unique words.
• Each list of words must be sorted in ascending order.
