Here is my code: function flatten (arr) { arr2 = []; for (let i = 0; i < arr.length; i++) { arr2.concat(arr[i]); } } return arr2; But...it doesn't seem to be working! Fix my code so that it correctly flattens the array. Examples - flatten ([[1, 2], [3, 4]]) → [] // Expected: [1, 2, 3, 4] flatten ([["a", "b"], ["c", "d"]]) // Expected: ["a", "b", "c", "d"] - [] flatten ([[true, false], [false, false]]) // Expected: [true, false, false, false] []

Java Programming (no copy-pastes, please) In Java, write two applications, a client and a server that communicate with each other according to the protocol: The connection is only maintained (authenticated) if the first thing the client sends is the message “OOP”; After the first authentication, the server will receive messages typed in by the client until he sends an “End” message; the server will just write the received messages on the screen; When the server receives the “End” message, it will start sending typed messages to the client, who will receive them and write them to the screen until an “End” message is sent to the client.
