        int num,res=0,minDigit,maxDigit;
        printf("Enter a number\n");
        scanf("%d",&num);
        maxDigit=minDigit=num%10;
        while(num)
        {
                res=num%10;
                if(res<minDigit)
                        minDigit=res;
                else if(res>maxDigit)
                        maxDigit=res;
                num=num/10;
        }
        printf("Min Digit = %d\nMax Digit = %d\n",minDigit,maxDigit);
        return 1;
