• Lecture 13 (02/26)

? In class assignments #12. Design a Ruby class that inherits from the inbuilt String class and adds an additional functionality to check if the string is a palindrome. Email your code by end of day 02/28.

• Lecture 12 (02/21)

? In class assignments #11. Design a Ruby class to process weather data from NCDC as discussed in class. You should be able to set a particular year and find the maximum temperature in that year. Email your code by end of day 02/26.

• Lecture 11 (02/19)

? In class assignments #10. Design a Ruby class to set and get a single line of text, check for substring, get the length and concatenate with another input string. Email your code by end of day 02/21.

• Lecture 10 (02/14)

? In class assignments #9. Each file in the folder 1951 is associated with a particular weather station. For example, the file 010230-99999-1951 contains recordings (multiple recordings per day) from the weather station id 010230 for the whole year of 1951. Similarly other files for other weather stations. Write a Ruby program that merges all the files in the folder into a single new file called "1951-recordings". You can place all the records from a particular weather station followed by all the records of another station and so on. Then compute the average global temperature for the year 1951. (Remember that the measurements were made at multiple times per day!) Use your regular team for this assignment. Submit your code by end of day 02/19 by email.

• Lecture 9 (02/12)

? In class assignments #7 and #8. Assignment #7: Complete previous assignment without number of players assumed ahead of time. Assignment #8: Compute the highest temperature in the years 1901 and 1902. (The data is here. Format information is available here.) Email your code for the two assignments (separately) by end of day 02/14.

• Lecture 8 (02/07)

? In class assignment #6. Build on the previous assignment to write a function to compute a tournament winner with 2^n number of players.

• Lecture 7 (02/05)

? In class assignment #5. Write a Ruby function that takes as input an array modeling a simple rock-paper-scissors game and returns the winning's players name. For example, if the input to the function is the array [["Alice", "Rock"], ["Bob", "Paper"]], the function should return the string "Paper". Name your file <lastName>.rb and email your code by identifying your team members by end of day 02/06.

• Lecture 6 (01/31)
? In class assignment #4. Write a Ruby function that takes as input an array of strings, groups them into anagrams and returns an array of anagram arrays. For example, if the input to your function is ["god", "dog", "no", "on", "google", "yahoo"] then the return value should be [["god", "dog"], ["no", "on"], ["google"], ["yahoo"]]. Write a Ruby program to demonstrate that the function works. Name your file as<lastName>.rb and email by end of day 02/01.

• Topics covered: Array operations in Ruby.
• Lecture 5 (01/29).
? Assignment #3. Write a Ruby program that reads a line from the user and checks if the line is a palindrome. You should ignore case and punctuation characters in deciding if the input is a palindrome. For example, "A man, a plan, a canal - Panama" is a palindrome. See other examples here. Assignment #2 posted. (See lecture 4 below.)

Topics covered: intro to Ruby: programming exercise.
