in reply to Re^5: Extract the odd and even columns seperately in the hash of arrays or some other data structure apart from arrays
in thread Extract the odd and even columns seperately in the hash of arrays or some other data structure apart from arrays

yeah there can be 1 million unique ids or may be there can be 500,000 ids where each id is repeated twice. In some cases I need to match the same ids also and in some cases I have to match the rows having same ids with the other rows i.e. the first row having a id 1 with first and second row having a id 2. Similarly, the second row having a id 1 with first and second row having a id 2. Thanks.
