A weather station program uses an algorithm to find the location with the lowest recorded rainfall.

State what should be written in place of the labels L1, L2, and L3 in the algorithm below to successfully identify and output the station with the lowest rainfall.

SUBROUTINE findMinRainfall(searchType, numSensors)
    sensorData ← [['140', '35', '210', '12', '88'],
                  ['North-Peak', 'East-Valley', 'West-Coast', 'South-Ridge', 'Central-Plains']]
    idx ← 0
    minRain ← 9999
    IF searchType = 'MINIMUM' THEN
        FOR k ← 0 TO numSensors - 1
            rain ← STRING_TO_INT(sensorData[L1][k])
            IF rain < minRain THEN
                minRain ← rain
                idx ← L2
            ENDIF
        ENDFOR
    ELSE
        OUTPUT 'operation not supported'
    ENDIF
    IF minRain ≠ 9999 THEN
        OUTPUT 'Lowest rainfall at ', sensorData[1][idx], ' is ', sensorData[0][idx], 'mm'
    ENDIF
ENDSUBROUTINE
