Anоther wаy tо mаnаge lоcks is the wound-wait system. Consider the following three transactions. T1: lock A; lock B; unlock A; unlock B T2: lock B; lock C; unlock B; unlock C T3: lock A; lock C; unlock A; unlock C Suppose we allow these transactions to execute in round-robin fashion. When it is a transaction's turn, it executes its next lock or unlock step if it can, and otherwise waits or wounds the holder of the lock, as appropriate. Assume that each transaction is given its deadlock timestamp the first time it executes a step. Determine the sequence of steps that the three transactions make, including all wound/rollback steps (which take place in a single round of the round-robin) and the restarts of transactions. Then, identify the true statement below about how many times a transaction is wounded or waits.
