    Hi i'm new to this place.. :eek: Great to be here..
    anyway, i'm having this problem with an assignment i have to complete.. it's regarding a prblem called non increasing partitions of n. i have to get the output
    4
    3 1
    2 2
    2 1 1
    1 1 1 1
    when given the input 4.. i already have an algorithm i tried out, but the only answer it gives in the end is 4.. i believe this is a recursive algorithm.. does anyone have any idea?

    I just came up with this code.. but it doesnt work from the 3rd line onwards.. :-(
    Code:
    #include<stdio.h>
    void partition(int no);
    int main()
    {
       int n=4;
    
       partition(n);
    
    }
    
    void partition(int no)
    {
       int j=0;
       int i;
       for(i=no; i>=1; i--)
       {
            printf(" %d , %d  \n", no-j, no-i);
            j++;
       }
    }

    you are increasing j to often try creating a for loop with j as well inside the I loop area.

    Also lthe length you have should be dynamic based on the length of N or you will never get 4 1's

    yeah.. datz the problem i'm havin.. anyway, i created a program so as to get the N from the user.. anyways, it gives the following result when n = 4 now....

    4
    3 1
    2 2
    2 1 1
    1 1
    1 1

    It doesn't even like this for any values beyond 4.. hmmmm
    Anyway, it's in a presentable form now atleast for the assignment purposes..

    The pattern is next line you represent any number as the sum of 2 numbers in the above line. Or simple words break the numbers as you move down the line numbers.
