An automated search-and-rescue drone uses an infrared sensor to scan a forest, representing the area as a $\times 4\,$ grid of temperature readings stored in a 2D array named thermal_grid. A specific reading of 100 indicates the infrared signature of an emergency beacon.

beacon_row = -1
beacon_col = -1
for y = 0 to 3
    for x = 0 to 3
        if thermal_grid[y, x] == 100 then
            beacon_row = y
            beacon_col = x
        endif
    next x
