Dear Group,
Thank you for the kind help. I could solve other portions of the code easily.
As this algorithm is an important algorithm so is its Wikipedia note, so I
changed subject line bit, in case future users try to solve any questions, they
may get the helps.
Thank you again especially to Ian.

Subhabrata Banerjee.
