Dr. Harrison is monitoring the temperature variation of a cryogenic storage unit over a 4-hour period.

The temperature sensor logs hourly integer readings in degrees Celsius. The input values from the log file TempSensor.txt are: -18, 35, -52, and 12.

Complete the trace table showing the execution of the program with these four inputs.

You may not need to use all the rows in the table.

1 temp = 0
2 min_temp = 80
3 max_temp = -80
4 line = ""

6 file = open("TempSensor.txt", "r")

8     temp = int(line)
9     if temp < min_temp:
10        min_temp = temp
11    if temp > max_temp:
12        max_temp = temp
13 print(min_temp, max_temp)
