be equal to 9. For example if the number is 9876543210, the
sum is 9+8+7+...+1+0 = 45. Sum of 4+5 = 9.

Answer / c.p.senthil

// The prototype in question is not exactly c language. but i tried to provide equivalent solution in c.

int SingleDigitSum(int num)
{
int hund, tens, ones;
int sum = 0;

sum = num;

do
{
hund = sum / 100;
sum = sum % 100;
tens = sum / 10;
ones = sum % 10;
sum = hund + tens + ones;
}
while(sum > 9);

return(sum);
}

boolean isVIPMobileNumber(String mobileNum, String operator)
{
int i, sum=0, zeroCnt=0;
int tens, ones;
boolean retValue = FALSE;

// check for Vodafone operator
if(strcmp("Vodafone", operator) == 0)
{
// validate length of mobile number including NULL
if(strlen(mobileNum) == 11)
{
// check for the number should not end with 8
if(mobileNum[9] != 8)
{
for(i=0; i<10; i++)
{
if(mobileNum[i] == '0') zeroCnt++;

sum += mobileNum[i];
}

// Atleast one 0 (Zero) should be exist in mobile number.
// The single digit sum of all the digits in the number should be equal to 9.

// maximum sum possible single digit sum = 9+9+9+9+9+9+9+9+9+9 = 90 = 9 + 0 = 9

if((zeroCnt != 0) && (SingleDigitSum(sum) == 9))
{
retValue = TRUE;
}
}
}
}
}
