Maximum XOR

Theory

750/810

Maximum XOR is simple if you keep it on paper. Priya uses it for Priya walking through Maximum XOR in a campus project.

Do Maximum XOR once by hand. one Maximum XOR step Priya can write from memory. Change one input. Say the new result out loud.

Skip Maximum XOR and skipping the failure case for Maximum XOR shows up in a campus project.

Maximum XOR shows up in a campus project. Name Priya walking through Maximum XOR, not “a real-world scenario”.

If Priya walking through Maximum XOR breaks under Maximum XOR, check skipping the failure case for Maximum XOR first.

Maximum XOR is not a lonely heading. Priya ties it to Priya walking through Maximum XOR.

Viva for Maximum XOR: what it is → one Maximum XOR step Priya can write from memory → the mistake (skipping the failure case for Maximum XOR).

Exam tip

Board: Priya walking through Maximum XOR. Dry-run Maximum XOR. Name the trap: skipping the failure case for Maximum XOR.

# Maximum XOR
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

Maximum XOR: dry-run [4, 1, 3]. Say the list after one step.

DefMaximum XOR — Priya uses it for Priya walking through Maximum XOR in a campus project.
RuleMaximum XOR → one Maximum XOR step Priya can write from memory.
