Q2.A salesman has to visit 5 cities the distance between the 5 cities are as follows:
To City
A B C D E
From City A[infi 7 6 8 4
B 7 infi 8 5 6
C 6 8 infi 9 7
D 8 5 9 infi 8
E 4 6 7 8 infi]
If the sales man starts from city A and has to come back to his starting point which route should he select so that the total distance covered is minimum.

B 3 infi 1 0 1
C 0 1 infi 2 0
D 4 0 2 infi 3
E 0 1 0 3 infi
The travel is given as A-->E-->B-->D-->C-->A
Distance=4+5+6+9+6
=30 Km
