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.
