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

what numbers would you input in order to find what it does?

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
