Algorithm: Word Frequency Counter

Data Structure: A dictionary where the keys are the words (in lowercase) and the values are the counts of how many times each word appears.

1. Start
2. Open the text file for reading.
3. Create an empty dictionary called wordFrequencies.
4. For each line in the file:

   • Read the line.
   • Convert the line to lowercase.
   • Split the line into individual words using whitespace as a delimiter.
   • For each word:

     • If the word is already a key in wordFrequencies:

       • Increment the value (count) associated with the word by 1.

     • Otherwise:

       • Add the word as a new key to wordFrequencies with a value of 1.

5. Print the wordFrequencies dictionary. This will show each word and its count.
6. Close the text file.
7. End
