Obtain the secret value The UnicornBox database contains a table of secrets for the developers: 1 CREATE TABLE IF NOT EXISTS secrets ( 2 id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, 3 secret TEXT 4 ); Developers can add secrets to the table using SQL INSERT statements.The cs161 user is using UnicornBox to store a le called ip.txt. cs161 is a special-purpose account on UnicornBox. It uses a separate login mechanism, so you won’t be able to log in as cs161, but you may still be able to change some of its les. Your task: Change the contents of cs161 user’s ip.txt le to be 161.161.161.161. At least one regular discussion section will be available on Zoom. Exam prep sections focus primarily on solving previous exam questions, and are 1 hour long. Extended-time sections (aka Bridge) cover material at a slower pace and more in-depth, and are 1.5 hours long. If a TA decides to host a hybrid section, they will post their Zoom link on Ed.
