Assume there is a print() function in Solidity that takes in any variable and prints a human-readable representation of the variable without quotes regardless of public/private access. Assume gas is zero. Currently, Tim has 10 ether. Matt has 10 ether. Minxing has 10 ether. Did you read this?

Consider the following questions happening in a single environment, meaning, question 2 happened after the action of question 1 has taken place. So, does this contract apply to all the questions in this quiz?

Tim’s address is 0xd95e068a69045ece32eecad394d86a9ac7b832ca. Tim hashed abi.encodePacked(true, “12345678") with keccak256 and got “c844hfksjc9didvnrrmf4hdusjznryfu” (Don’t worry if you don’t understand this part.) Tim called constructor(“c844hfksjc9didvnrrmf4hdusjznryfu”) with a value of 1 ether. You called print(player1). What would Solidity print?
