An algorithm has been written to control the automatic safety shutdown threshold of a drone based on the payload module connected to it.

Figure 1

1      payload ← USERINPUT
2      IF payload = 'camera' THEN
3          max_time ← 20
4      ELSE IF payload = 'lidar' THEN
5          m_time ← 12
6      ELSE IF payload = 'sensor_pack' THEN
7          max_time ← 15
8      ELSE
9          OUTPUT 'invalid payload'
10     ENDIF
11     FOR minute ← 1 TO max_time
12         IF minute > 10 THEN
13             SIGNAL_WARNING('low battery warning')
14         ELSE
15             SIGNAL_WARNING('battery normal')
16         ENDIF
17     ENDFOR

Write one line of code that would correct the error found in the algorithm in Figure 1.
