An A2Casobject represents two locations for values that can be read individually and be modified by a2cas(). If both locations have the corresponding expected value se 0 ande1, then a call toa2cas(e0,e1,v)will write v to exactly one of the two locations, chosen non deterministically. What is the consensus number of thea2cas ()object? Prove your claim.
