Step 1 of 5 · Generate
Create a function that finds duplicate values in a list.
def find_duplicates(items):
seen = set()
duplicates = []
for item in items:
if item in seen:
duplicates.append(item)
else:
seen.add(item)
return duplicatesEverything you need to build faster

AI does the work. You stay in control.
CodeForge is built around a developer workflow: generate, verify, repair, run, and improve. The goal is faster engineering without giving up visibility, control, or ownership of your code.
*Capabilities and limits vary by product, plan, and workflow. This comparison describes broad publicly advertised capabilities, not a claim that competitors lack them.
