01      56      JUMP
02      FD      REVERT
03      FD      REVERT
04      5B      JUMPDEST
05      00      STOP

? Enter the calldata: 

Solution

CALLDATASIZE pushes the size of calldata onto the stack, and JUMP will jump to that address.

The objective is to jump to address 0x04, so the size of our calldata should be 4. For example, you can use 0xdeadbeef.
