There have been many comments on this being a homework assignment so I'll post no code. However, as I looked at the problem I realised that nothing jumped out at me as to how I would solve this problem so I'll just put down some of my thinking and let any other monks comment.

  • Open the file
  • Read in line by line seperating each line by a space making the 1st element of the line the key of a hash. The second and third element of the line would then become $matrix{key} = [meal, TimeOfDay]
  • Print a line of the headings I.e. Food Morning Noon Night
  • Process each key in the hash checking the second element of the value array in the hash for where you position the "type of meal". - What module could be used for the formatting of the output table..?
  • Close the input file

    • Does that make any sense..? Is there a better way to tackle this problem..?
