Modulo By 2 A Given Input n

All the code below is used to simply do: input % 2 & return the result

Runtime Code

60 PUSH1 0x04 // save input in memory
35 CALLDATALOAD
60 PUSH1 0x00
52 MSTORE // mstore(0, calldataload(4))
60 PUSH1 0x02
60 PUSH1 0x00
51 MLOAD
06 MOD // mod((mload(0), 2)
60 PUSH1 0x00
52 MSTORE // override memory at index 0 to store modulo result
60 PUSH1 0x20
60 PUSH1 0x00
F3 RETURN // return input from memory at index 0 on 32 bytes (0x20)

Concatenation of 20 bytes from above: 60043560005260026000510660005260206000f3
