sir......the output that i an getting for this solution is not the answer which is given in the sample output.The order is different.
the sample output is suppose to be:
for Input N=5
Output : Given number 5
Combinations :
1 1 1 1 1
1 1 1 2
1 2 2
1 1 3
1 4
2 3
but the output that i an getting is:
Enter a number : 5
Combinations :
1 4
1 1 3
1 1 1 2
1 1 1 1 1
2 3
2 2 1
wat kind of doubt is it??? dude dont worry the output u gt is correct... the order does nt matter dont b stupid!
output is same
only the order is different.
the recursive function is printing the output in this form
bt ma frnd...the ordr mattrs....
u shld prnt xactly wats gvn in the sample o/p
yes the order matters in the print out dat u take the sample out put is very inpt.......the examiner checks 4 the sample out put first.....and dat shud b in da correct ordr.....
So wait. Is there a corrected program for this?
yup...........my frnd said dat she'll send it to me but den she didnt send it till nw...........does ny 1 kno da soln 4 these.......
The Hamming distance between two bit patterns of same length is the number of bit positions at which they (bits) differ. For example, the Hamming distance between 11101010 and 00011001 is 6, since they differ at 1st , 2nd, 3rd , 4th, 7th, and 8th positions.
Write a program, which inputs 2 non-negative integers, determines their binary representation and outputs the Hamming distance between their binary representations.
Given a time in numbers we can convert it into words. For example
5 : 00 Five o'clock
5 : 10 Ten minutes past Five
5 : 15 Quarter past Five
5 : 30 Half past Five
5 : 40 Twenty minutes to Six
5 : 45 Quarter to Six
5 : 47 Thirteen minutes to Six
Write a program which first inputs two integers, the first between 1 to 12 (both inclusive) and second between 0 to 59 (both inclusive) and prints out the time they represent, in words. Your program should follow the format of the examples above.
SAMPLE DATA :
Input Time : 3,0
Output 3 : 00 Three o'clock
Input Time : 7,29
Output 7 : 29 Twenty nine minutes past Seven
Input Time : 6,34
Output 6 : 34 Twenty six minutes to Seven
Input Time : 12,1
Output 12 : 01 One minute past Twelve
Input Time : 12,45
Output 12 : 45 Quarter to one
Input Time : 10,59
Output 10 : 59 One minutes to Eleven
Input Time : 14,60
Output Incorrect input
Yeah the hamming one is pretty easy. Try it yourself? Just take some time and you'll get the solution. And when your friend sends it, do you mind posting it here?
thnx........i am waitin 4 her 2 send it.....but den its too late nw.......may b som thing wnt wrong wid her net.......i dnt think she'll send it nw........:(....
Oh great. :| Thanks for the help anyway.
The hamming program - just try digit extraction and comparing like that. Just use a counter to keep adding the number of unequal terms. That's about it, right?
Or you can turn it into a string, and then compare character-wise.

There is better way than this.
This prg is not fully correct but Time prg is correct
Does anyone know what exactly is coming?And the order is important for this one,right?.Can someone post it here?
hw was da xam??????...........me vry happy wid wat evr came..:):):):).........
@jojo.....thnx 4 ur efforts in puttin the prog up................
