DS4UX (Spring 2016)/Day 2 coding challenge: Difference between revisions

Latest revision as of 23:15, 10 April 2016

Each of the challenges this week will ask you to modify and work with code in the Wordplay project which you should have installed and begun working with in class.

As always, it's not essential that you solve or get through all of these — I'm not grading your answers on these. That said, being able to work through at least many of them is a good sign that you have mastered the concepts for the week. It is always fine to collaborate or work together on these problem sets. The only thing I ask is that you do not broadcast answers before Sunday at midnight on Canvas.

Note: before attempting these, be sure to review working within loops.

Challenges[edit]

Challenges about finding words:

Find all words that start with 'a' and are 9 or more letters long.
What is the longest word that starts with a 'q'?
Find all words that end with 'nge'
You need a word that matches "a*ey" (here "*" means any letter). Are there any words that match?
Print every other word that matches the condition in (1) above.
Find the longest string where no character is used > 1 time.

Now we're going to start finding points! You can use scrabble.scores to get the scores for every letter. But we're going to cheat: assume you have all the letters.

7. What is the most valuable word in the dictionary, and how much is it worth?

8. You want to match a word that starts with an 'a', has an 'e' in the 4th slot, and is no more than 7 characters long. What is the best word you can play?

9. Make a list that shows the most valuable word that starts with each letter. Example:

a: apophthegmatize, 37
c: chiquichiquis, 41
b: bezzazzes, 47
e: embezzlements, 37
d: decitizenizing, 36
.....

 == Challenges ==
-# Search for your own name. Are there both boys and girls that have your name? Is it more popular for one group than for the other?
+Challenges about finding words:
-# Are there more boys names or girls names? What about for particular letters? What about for every letter?
-# What is the longest name in the dataset?
+# Find all words that start with 'a' and are 9 or more letters long.
-# How many boys and girls are described in the dataset (i.e., how many boys and girls born in 2013 have names given to at least four others)?
+# What is the longest word that starts with a 'q'?
-# How many boys names are also girls names? How many girls names are also boys names?
+# Find all words that end with 'nge'
-# How many names are subsets of other names?
+# You need a word that matches "a*ey" (here "*" means any letter). Are there any words that match?
-# Write a program that will take a name as input and return the number of girls and boys with that name.
+# Print every other word that matches the condition in (1) above.
-# What is the most popular girls name that is also a boys name?
+# Find the longest string where no character is used > 1 time.
-# Take a prefix as input and print the number of boys and girls with that prefix. (i.e., "m" would list babies whose names start with "m" and "ma" would list babies whose names start with "ma", etc).
