Re: [algogeeks] Assembly Output ADOBE question
This code could've been intended to calculate some non-negative integer power of another integer, but the whole stack thing with the order of pushes and pops is weird. There are no such registers and instructions. What is it ?? cheers On Sat, Oct 13, 2012 at 6:10 PM, Ashok Varma wrote: > what does the stack initially hold ? > > > On Sat, Oct 13, 2012 at 4:18 PM, Akshat Sapra wrote: > >> >> DETERMINE THE OUTPUT R1,R2,R3 ARE THREE REGISTERS >> >> START :POP R1 >> POP R2 >> COMPARE R2,0 >> JUMP_EQ DONE_Z >> PUSH R2 >> PUSH R1 >> SUBTRATCT R2,1 >> PUSH R2 >> CALL START >> POP R3 >> POP R1 >> POP R2 >> MULTIPLY R3,R2 >> JUMP DONE >> DONE_Z:MOVE R3,1 >> DONE:PUSH R3 >> PUSH R1 >> RETURN >> >> -- >> You received this message because you are subscribed to the Google Groups >> "Algorithm Geeks" group. >> To post to this group, send email to algogeeks@googlegroups.com. >> To unsubscribe from this group, send email to >> algogeeks+unsubscr...@googlegroups.com. >> For more options, visit this group at >> http://groups.google.com/group/algogeeks?hl=en. >> > > -- > You received this message because you are subscribed to the Google Groups > "Algorithm Geeks" group. > To post to this group, send email to algogeeks@googlegroups.com. > To unsubscribe from this group, send email to > algogeeks+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/algogeeks?hl=en. > -- Sharad Dixit -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.

Re: [algogeeks] Switch doubt in C

If a matching label is found, execution proceeds from there. Control then
passes down through all remaining labels within the switch statement.

Re: [algogeeks] doubt about macro.......
Think #define as a simple text substitution macro.
Assume you are the preprocessor. Copy/paste the exact code for the macro
into the places where your program tried to use and then replace the macro
parameters with the arguments that you used to invoke the macro.
The advantage of a macro is that it can be type-neutral (also disadvantage
sometimes ), and it is inlined directly into the code, so there is not any
function call overhead.
correct me if am wrong :D

Re: [algogeeks] Re: check Similar array
Can we use concept of prime number as fundamental theorem of arithmetic i.e
every number has a unique factorization into primes (
http://en.wikipedia.org/wiki/Fundamental_theorem_of_arithmetic) and then
multiply them together.
e.g
A1[3] = { 2,3,4} => secondprime*thirdprime*forthprime = 2 * 3 * 5 = 30
A2[3] = { 3,2,4} => 3rdprime * 2ndprime* 4thprime = 3 * 2 * 5 =30
