Do the root shuffle - clarification required

I am trying to solve this challenge problem and want some clarification please. When the question states:

{f(b1),f(b2)}={b1,b2}

Does this imply:

f(b1) = b1

f(b2) = b2

No. For example, if you have the set {3,2} and {2,3}, they are the same set, but it doesn't necessarily imply that 3 = 2. Taehyung Kim · 3 years, 3 months ago
