Final Project - Individual (Ethan Tran)

Code Contribution - Spacebook

Image to Base64 Code

• Specify the base URL path so that all endpoints are relative to /image
• GET request mapping fetches all records from our database

• The POST request saves the uploaded file and fileName
• Uploaded image is then encoded to Base64 string, so that it can be stored as text in our database
• A new file is then made with the fileName and the encoded string

• Images can be accessed via the endpoint "/image/{fileName}"
• If the image is present, then the Base64 string is retrieved and decoded back into binary format

• Check format of file and adjust media type accordingly

Frontend integration

Image Viewer

• Fetches the image from the backend based off value of fileName input by the user
• URL is created for the blob (binary large object) to use it as an image source on the page

CollegeBoard Quiz

Question 19

Topic 3.6 - Equivalent Boolean Expressions

• I read this problem wrong, the opposite of greater than is less than or equal. Thus, the opposite of (b > 7) is (b <= 7).

Question 37

Topic 4.1 - While Loops

• Choice I works. Choice III works also, as it will cause the while loop to iterate while x is less than 7. The variable x is assigned 1 to start and then incremented by 2. It will be assigned the values 1, 3, 5 and then 7. When x has the value 7, the loop will terminate. The output will be 1, 3, 5.
