In the problem statement it is said that length of roads will be maximum 1000.
But in Test case 4 and more other test case it was given more than 1000.
Can anyone clarify me whether I have wrong understanding or not.
Thanks.

Sometimes you need to use more than one road to get from one town to another, so the shortest distance could be larger that 1000.
Also:
"Then there follow n lines with n integer numbers each — the matrix of shortest distances"
Test 4:
The length of planned roads cannot be larger than 1000, but the shortest distance using existing roads can be larger.
P.S. Sorry for my poor English
