Samantha sat down at the fifth computer in her university's computer lab, hoping to retrieve the data she had put into that computer a week previously. However, when she looks at the computer monitor, she sees the following message:
Access denied. Please enter the three-digit code to proceed. If you enter an incorrect code, all the data on this computer will be wiped. You have one chance.
Not knowing the code, Samantha frantically looks around on the desk next to her, and notices an unusually marked sheet of graph paper. She takes a picture of it and sends it here, hoping that it might hold the clues to the three-digit code the computer requests. However, she can't make sense of it. This is where you come in. Can you figure the three-digit code out?
