Use cases

I went to the supermarket, and the total value of the purchase was: $180. In my wallet I have the following notes:

• $10
• $20 x 2
• $50 x 4
• $100

Then:

const idealvalues = require("idealvalues");

const values = idealvalues(180, [10, 20, 20, 50, 50, 50, 50, 100]);

console.log(values);

Output

[ 50, 100, 10, 20 ]

To pay I need to pass the following notes:

• $50
• $100
• $10
• $20
