Which Solidity keyword prevents state variable shadowing?

Tip: Click "Play" to reveal options and start playing.

#A

#B

#C

Why is calldata preferred for router functions?

Tip: Click "Play" to reveal options and start playing.

#A

#B

#C

#D

Explanation:
Calldata avoids copying user inputs into memory, significantly reducing gas usage for large payloads. Router contracts receive untrusted inputs, so avoiding memory expansion is both cheaper and safer. This is why AMMs and DEX routers heavily rely on calldata
