Question

Example:

-6 3 -1 -3 7

-3 -4 1 3 -7

-6 2 -1 8 4

After sorting:

1 -7 -3 5 -10

-3 -6 -2 1 4

-6 3 -1 -3 7

-3 -4 -7 1 3

-6 2 -1 8 4

Answer 1

run a loop for moving through all rows of the matrix ,
if rowIndex%2==1 , then run a loop for replacing posn of -ve elemeny with +ve element ... ie if 2 , -1 ...then make it -1 ,2 , this will not even disturb the order .
//edit : no code , thats the way I suggested
//true learner must give a try by himself first .
