I am in desperate need of help! I am having an issue inserting the word into the correct list. Each array index is a letter of the alphabet, and the words need to be put into the correct index according to the first letter of the word. Can I get some help with fixing this issue with my insertWord function?

Here is the text file I am using:

easy but I feel I am getting better. One day when I am
out of the military I hope to work for some IT business.
The job can't be part-time either!

Better use maps than double link list.
