Write a JavaScript program which accepts amount in rupees as input (integer) within Range from

Rs. 100 to Rs. 100000 and then asks the user for particular currency note preference and display the total

number of currency notes of Rs. 500, 100, 50, 20, 10, 5, and 1. The user can be given a maximum of 200

For example: when a user enters a number, Rs. 57477 and enters 50 notes as his preferred choice, the

results would be like this.

Currency Note : Number

500 : 94

100 : 4

50 : 200

20 : 3

10 : 1

5 : 1

1 : 2
