Utilizing pprof golang utility to monitor program behaviour(execution time, memory usage, goroutines e.t.c) to understand time and resource utilization better

  //Simulate some CPU-intensive work
  for i:= 0; i< 1000000; i++ {
    _ = i * 1
  }
  
  //Allow time for all CPU usage to be captured
  time.Sleep(2 * time.Second)
