Re: [algogeeks] OS question..
I think the answer to Q1 may "Yes". Cause the virtual memory of program is limited, they need logically contiguous memory, and have limit from OS and processor(32-bit, or 64-bit) yet. I have no idea about Q2. On Mon, Nov 5, 2012 at 4:30 AM, manish wrote: > Q1. If we have infinite memory, then do we still be needing paging? > Q2.

[algogeeks] Re: swap objects without temp variable
@Manish: Sure. a = a + b; b = a - b; a = a - b; In 2-s complement arithmetic, it works even if a + b overflows.

[algogeeks] swap objects without temp variable
Swapping two objects (not integers/chars),without using temp...? my solution is using xor operation..is that right and ny other solutions ? -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.

[algogeeks] OS question..
Q1. If we have infinite memory, then do we still be needing paging? Q2. Given only 8bits registers, you have to find average of 4 bit registers values without using any operation involving 16 bit calculations. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
