hello, i need help with this sub program, everything ele works fine except the subprogram that should compute the smallest and largest number in the array

```
#include<conio.h>
#include<stdio.h>
#define MAX 10
int input(void);
int range(int i,int *s1,int *s2,int *s3,int *l1,int *l2,int *l3,int f[MAX],int hf[MAX],int lf[MAX]);

char choice, choice2;
clrscr();
do{
do{if(i==10)
{ printf("\n\n\t sorry,!!! this array is full " );
getch(); }
else{ n=input();
f[i]=n;
if(f[i] >=50 )
{ hf[a]=f[i];
a++; }
else

b++; }

}

scanf(" %c",&choice );
