    how to pick the basic cases for this function..

    in order to know what it does
    Code:
    void what(int n, int limit, int* answer, int place){ 
    int i;
       	if (n > 0)
    	   for (i=min(n,limit); i>0; i--){
    		   answer[place]=i; 
    		   answer[place+1]=-1;
    		   what(n-i, i, answer, place+1);
    		   answer[place]=-1;
    	   }
       	else{
    	   for (i=0; answer[i]!=-1; i++)
    		printf("%d ", answer[i]);
    	   printf("\n");
       	}
     }

    call the function in main() function with different values of n and place(preferably at boundary values) and observe the output
    Code:
    printf("%c%c%c%c%c%c%c",0x68,0x68^0xd,0x68|0x4,0x68|0x4,0x68|0xf,0x68^0x49,0x68^0x62);

    n=-1 and n=0 and n=1 for starters, as right at the beginning you got n>0

    though its really hard for me to tell...as i dont have any idea what its about...its upto you...actually
    Code:
    printf("%c%c%c%c%c%c%c",0x68,0x68^0xd,0x68|0x4,0x68|0x4,0x68|0xf,0x68^0x49,0x68^0x62);
