Python exercises
Early assignments in graphics, recursion, and search.
Checking an N-queens board
The board is a list of lists of Boolean values. The validation code checks rows, columns, and the two diagonal directions for attacking queens. The graphical interface lets a user toggle squares, so the same checks can be tried on valid and invalid arrangements.
Searching and keeping state
Other short assignments cover binary search, counters, timers, and a graph-based text adventure. They introduced different ways to represent state: a shrinking search interval, an object’s fields, or the current vertex in a story graph.
Course scaffolding
These are early exercises rather than a single application. Several use supplied graphics and testing code, including cs1lib and the N-queens board interface. The repository retains the original course credits.
