Show me the code!

Warm up

Today we will have a pair programming activity.

Don't worry, this first activity is just a warm up. It won't be part of your grade in any way.

We'll work on some problems from LeetCode.com so you can get a sense of the types of problems we'll be working in this course.

Why pairs?

You can discuss and brainstorm ideas with someone else.

It's harder to give up and just google the answer 😉

Easy problems

You should be able to complete most of them during this class:

• https://leetcode.com/problems/robot-return-to-origin/
• https://leetcode.com/problems/relative-ranks/
• https://leetcode.com/problems/is-subsequence/

Medium problems

These are more challenging. Finding an efficient solution is not trivial.

• https://leetcode.com/problems/longest-palindromic-substring/
• https://leetcode.com/problems/validate-binary-search-tree/

Hard problems

If you completed all problems up to this point, congrats! You've done really well!

Here's one final challenge for you:
