#include<stdio.h>




int calculateDiscount(int billAmount){
	int bill_amount=billAmount;
	int sumOddDigits=0;
	int sumEvenDigits =0;
	while(bill_amount>0)    
	{    
		int digit=bill_amount%10; 
		if(digit%2==0){
			sumEvenDigits+=digit;
		}else{
			sumOddDigits+=digit;
		}
		bill_amount=bill_amount/10;    
	}  
	return sumOddDigits*sumEvenDigits;
}


int main(){
	int billAmount=0;
	int discount=0;
	int totalBill=0;


	printf("Enter the bill amount: ");
	scanf("%d",&billAmount);
	discount=calculateDiscount(billAmount);


	totalBill=discount+billAmount;
