WalkthroughA new Kotlin file, Changes
Poem
Impact AnalysisIntroduction of new public Kotlin entities with multiple syntactic and semantic errorsA new Kotlin source file introduces several public classes, functions, and interfaces, but the code contains numerous syntactic and semantic errors that will prevent successful compilation and usage. Users or API consumers attempting to use these entities will encounter build failures and runtime issues, making the new functionality inaccessible or unreliable. Attempt to compile and run the code to verify that all public APIs are accessible and function as intended. Test error handling, edge cases, and ensure that all declared entities behave correctly and do not introduce regressions or runtime failures. 🔍 Related Files

Handle division by zero.
Callingdivide(10, 0) will cause an ArithmeticException at runtime.
Either change the divisor to a non-zero value or add error handling in thedivide function.
🤖 Prompt for AI Agents
In test.kt at line 14, the code calls divide(10, 0), which causes a division byzero error at runtime. To fix this, either change the divisor from 0 to anon-zero value or modify the divide function to handle division by zero bychecking if the divisor is zero and returning an appropriate result or throwinga controlled exception.| fun mismatchedBraces() { | ||
