  • Define bubbleSorting function that takes an array as input and sorts the array based on the length of each element.
  • Define sortSentencesOfAFile function that does the following:
    • Initialize a list.
    • Open the input.txt file in read mode.
    • Append each line in the file to the list.
    • Remove the duplicates from the list.
    • Use the bubbleSorting function to sort the elements of the refined list.
    • Call the writeSortedLinesToAFile function using the sorted list as the argument.
  • Define the writeSortedLinesToAFile function as follows:
    • Open the output.txt file in write mode.
    • Write the elements of the sorted array as each line into the file.
