Question 1
A bank intends to
design a program to display the denomination of an input amount, up to 5
digits. The available denomination with the bank are of rupees 1000 , 500 , 100
, 50 , 20 , 10 , 5 , 2 , and 1.
Design a program to
accept the amount from the user and display the break-up in descending order of
denomination. (i.e. preference should be given to the highest denomination
available) along with the total number of notes. [Note: Only the denomination used
should be displayed]. Also print the amount in words according to the digits.
Example 1
INPUT: 14856
OUTPUT:
ONE FOUR EIGHT FIVE
SIX
DENOMINATION :
1000
x
14 = 14000
500
x 1
= 500
100
x 3
= 300
50
x 1
= 50
5
x 1
= 5
1
x 1
= 1
TOTAL = 14856
TOTAL NUMBER OF NOTES
= 21

int i, totalNotes = 0;
BufferedReader br=new
BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the
Amount:");
amount=Integer.parseInt(br.readLine());
// Checking for the entered amount not
more then 100000
if(amount >99999)
{
System.out.println("Invalid
Amount…");
return;
}
temp = amount;
// Reverse the amount, example 3456
into 6543
// for displaying as THREE FOUR FIVE
SIX
while(temp !=0)
{
rev=rev*10+temp%10;
temp=temp/10;
}
System.out.print("Amount in words
:");
// Display the note in words
while(rev!=0)
{
rem=rev%10; // Mod division for
reminder
for(i=0;i<10;i++)
{
if(rem==i)
System.out.print(denomiation1[i]);
}
rev=rev/10; // Ineger division
}
i = 0;
// Display the denominators notes
System.out.print("\n\nDENOMINATION:\n");
System.out.print("============:\n");
while (amount!=0)
{
rev=amount/denomination[i];
if(rev!=0)
{
System.out.println(denomination[i]+"\t X " + rev +

totalNotes+=rev;
}
amount=amount % denomination[i];
i++;
}
System.out.println("TOTAL NUMBER
