A 4x4 game board tracks the coordinates of a hidden item marked with the character 'T'. The rest of the board contains empty values marked with 'E' as shown in the grid below.

Grid Layout

	Col 0	Col 1	Col 2	Col 3
Row 0	E	E	E	E
Row 1	E	E	T	E
Row 2	E	E	E	E
Row 3	E	E	E	E

Program Code

for r in range(4):
    for c in range(4):
        if checkCell(r, c) == "T":
            target_r = r
            target_c = c

Explain the purpose of the first iteration structure (for r in range(4)) in this program.
