No, if it was the first field all the time, I would never have posted this.
I kindly request you to look at my input again - if A B was encountered previously, when you next see B B it needs to be assigned to A.
I wanted to only provide a simple example but I guess I made it too simple and now appear not so smart.
Lets add some more.
Input
A A
A X
C D
E F
X L
A B
O O
P P
M N
B B
Output
A A A
A X A
C D C
E F E
X L X
A B A
O O O
T X X
E E E
P P P
M N M
B B A
My apologies, this is literally the first time I am posting questions in a programming forum. Please help me with further queries as you deem necessary.
