Welcome to your interview.
The question is on your right: Shortest Path in Grid. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Given a 2D matrix, find the shortest path from the top-left to the bottom-right corner using dynamic programming or graph traversal.
