TED-Ed: Can you solve the risky disk riddle? | James Tanton

The video tutorial explains a problem involving malware corrupting one of four disks in a mainframe. The solution involves using binary code to identify the corrupted disk by flipping a switch. The tutorial explores different scenarios and introduces the concept of parity to solve the problem. The strategy works for any mainframe with disks that are a power of two.

What mathematical operation is suggested to determine the corrupted disk?

What is the significance of treating twos as zeros in the context of this problem?

How can the sum of the lit disks help in identifying the corrupted disk?
