The description of my problem is here-
Suppose I have an array of arrays-
1.1) 23445
1.2) 2144
1.3) 77988
1.4) 545
1.5) 52358
2.1) 2356
2.2)7878
2.3)531
2.4)78
2.5)78090
3.1) 578689
3.2) 90877
3.3) 1345
3.4) 422
3.5) 64
.....
....
...
Now i need to compare 1.1 , 2.1, 3.1 ... and find the greatest among them. In the same way wid 1.2, 2.2, 3.2.....1.3, 2.3, 3.3 Does anybody have an idea how to implement this one?
