## ES242. Data Structures and Algorithms I.

##### Lab 03

Theme: Stacks

### The Cardstack Data Structure

## List of Practice Problems

- Compilers - a slight adaptation of the second problem in this lab.
- Alternating Current - try to come up with a characterization of when the wires can be untangled in terms of the symbols.
- Largest Rectangle in a Histogram - a fun problem. See if you can make use of the cardstack!
