The following diagram shows a timeline of events a, b, ... k, l on four processes (P₀, P₁, P₂, P₃). Each process assigns vector timestamps to events, with each process' counter initialized to 0 and incremented prior to each event. Hence, event a is assigned a vector timestamp of . What is the vector timestamp of event g on P₁?
