Byzantine Faults Example

Consider 3 processors P1, P2, P3, which receive values of 100, 99, and 103 respectively. Suppose P2 has failed in a byzantine why, and tells P1 that it has received value 200, but it tells P3 that the value is 23. In such a scenario, P1 would consider 103 to be the midpoint, while P2 and P3 will think that 100 is the midpoint.
