Step 1: Understand the algorithm. The problem describes an event counter that processes a stream of event codes. • If an event code is less than or equal to 2 (), the counter is incremented by 1. • If an event code is greater than 2 (i.e., 3 in this context), the counter remains unchanged.
Step 2: Initialize the counter and process the event stream. The initial count of events is 0. The event stream is .
• For the first event code, : Since , the counter increments. Counter = .
• For the second event code, : Since , the counter does not change. Counter = .
• For the third event code, : Since , the counter increments. Counter = .
• For the fourth event code, : Since , the counter increments. Counter = .
• For the fifth event code, : Since , the counter does not change. Counter = .
• For the sixth event code, : Since , the counter increments. Counter = .
Step 3: State the final count. After processing all events in the stream, the final value of the counter is 4.
The correct option is 4.
