Dear sir....I beg thousand perdons....I expected my output to be {{1,3},{7,9}}....
And I ave tried ALL the codes you have referred....and it is still undone.....some of your codes are not working in my compiler....probably because it is very old one...
I have tried equivalent codes in each and every loop....
I will still try to work it out....I have spend the whole yesterday behind this one....
I will use more debugging codes and will give you the ultimate feedback.....thanks for all your advises....
