Would you ship AI-generated code without review?

Sometimes it looks like the perfect solution at first glance…
Then you run it and you realize:
looking right isn't the same as being right. ☝️

Now it's your turn to be the reviewer:
Can you spot what the AI missed?

🙃 AI Fail Moments

Have you ever had a "Wait…, what?" moment while using AI for coding, code reviews, or debugging?

• Complexity gaslighting: Says it's $O(n)$, but it's actually $O(n^3)$
• Pattern mismatch: Applies sliding window to a DP problem
• The Hallucinator: Invents a non-existent function—and confidently explains it
• The "I'm Sorry" Loop: Keeps apologizing but never fixes the issue

🐞 AI Code Fix Challenge

Can you spot where AI-generated code breaks, and how to prevent it?
Common pitfalls include:

• Incorrect edge case handling
• Missing branches or flawed logic
• Accidental mutation of mutable objects

Take a look at this AI-generated snippet for merging intervals. Can you spot the bug?

def merge(intervals):
    intervals.sort(key=lambda x: x[0])
    merged = []
    for i in range(len(intervals)):
        if not merged or merged[-1][1] < intervals[i][0]:
            merged.append(intervals[i])
        else:
            merged[-1][1] = intervals[i][1] 
    return merged

📌 Activity

• Find the bug: What's wrong with this code? In which test cases will it fail?
• Fix it: Provide the correct logic
• Prompt Design: In one sentence, how would you instruct AI to avoid this mistake?
