Consider the path be A-B-C-F.
Determine the sum of path A-B-C-F.
[tex]\begin{gathered} \text{ABCF}=-9.4+8.3-7.6+4.9 \\ =-3.8 \end{gathered}[/tex]
Not equal to -2. Incorrect path.
Consider the second path A-B-E-F.
Determine the sum of path A-B-E-F.
[tex]\begin{gathered} \text{ ABEF=}-9.4+8.3-5.8+4.9 \\ =-2 \end{gathered}[/tex]
The sum of path A-B-E-F is equal to -2, which is equal to answer -2. So code is,
A B E F .
