Study Guide for Test 1 (22 Feb 2017)

* The test will be on Wednesday, 22 Feb 2017. The test will be
  held during scheduled class times. It will be closed book and
  closed notes. 

* You are responsible for the material in Liang's book from chapters
  1 through 6.

* Questions are of two types - write code or interpret code.

* You will define variables, i.e. write meaningful variable names and
  their values.

* You will evaluate expressions given certain input values. This will
  involve all the operators that were discussed in class not bitwise
  or shift.

* You will write Boolean expressions that evaluate to True given a 
  set of conditions.  
  
* You will create truth tables for Boolean expressions that will
  involve Boolean operators not, and, or, xor. The Boolean expressions
  will involve just two Boolean variables (let us say A and B) and your
  truth tables will have all possible permutations of A and B.

* There will be questions on conditionals. You will either write 
  conditional statements given a set of criteria or you will
  be given a conditional statements and a set of input values and
  you should be able to state what the result or output of those
  conditionals will be.

* There will be questions on while and for loops. You should know
  the use of sentinel values and boolean flags. You also be familiar
  with break and continue within a loop.

* You can be asked to draw patterns using nested loops.

* You are responsible for these built-in functions:
  - abs (x)
  - bool (x)
  - chr (x)
  - eval (expr)
  - float (x)
  - format ()
  - input (prompt)
  - int (x)
  - len ()
  - list ()
  - max ()
  - min ()
  - ord (x)
  - pow ()
  - print ()
  - range ()
  - round (x, n)
  - str (x)
  - sum ()
  - type (x)

* From the Math library you are responsible for
  - ceil ()
  - floor ()
  - log (x, base)
  - pow ()
  - sqrt ()
  - hypot ()
  - math.pi

* From the Random Library you are responsible for
  - randint ()
  - randrange ()
  - random ()
  - uniform ()
  - choice ()
  - shuffle ()
  - sample ()

* You will write short functions or use functions that we have
  already written in class to solve problems. The user defined
  functions that we have developed in class are:
  - sum_digits (n)
  - rev_num (n)
  - is_palindromic (n)
  - is_prime (n)
  - sum_divisors (n)

* You will have to write a full length program that will involve
  user input, computations involving operators and functions, 
  conditionals, loops, and output.

* Go through all the worked pieces of code in the book and then
  do the exercises at the end of each chapter.

* Do the Logic-1 and Logic-2 problems from both the Python and
  Java sections in CodingBat.
