Question 21

Easy

An agricultural drone is programmed to scan a $\times 6\,$ grid of land sectors to locate a sector where the soil is classified as "Arid".

Figure 1: Scan Algorithm

target_row = -1
target_col = -1
for r = 0 to 5
    for c = 0 to 5
        if checkMoisture(r, c) == "Arid" then
            target_row = r
            target_col = c
        endif
    next c
next r

Figure 2: Moisture Grid State

	Column 0	Column 1	Column 2	Column 3	Column 4	Column 5
Row 0	Moist	Moist	Moist	Moist	Moist	Moist
Row 1	Moist	Moist	Moist	Moist	Moist	Moist
Row 2	Moist	Arid	Moist	Moist	Moist	Moist
Row 3	Moist	Moist	Moist	Moist	Moist	Moist
Row 4	Moist	Moist	Moist	Moist	Moist	Moist
Row 5	Moist	Moist	Moist	Moist	Moist	Moist

Explain the purpose of the inner iteration structure (the loop using the variable c) in the algorithm in Figure 1.
