Given a list of integers, this function will return a dictionary with the integers as keys and the number of times each integer appears in the list as values.

Given a list of words, this Python program finds the longest word that can be made by concatenating other words from the list. For example, given the input ["cat", "cats ", "dog", "dogs", "pig", "pigs"], the output would be "catsdogspigs".

This technical problem involves creating a function that takes in a list of words and returns a dictionary with the words as the keys and the number of times the word appears in the list as the values .
