Description

This is a simple web service written in Rust using the Actix web framework. The service has a single endpoint that returns a JSON response.

The demo app is the Greedy Algorithm to find Minimum number of Coins.

Say we have only have 1, 5, 10, 25 cents and we need to give 1 dollar and 3 cents in total to someone. The greedy algorithm will suggest us to hand in 25, 25, 25, 25, 1, 1 and 1 cent coins. This app will return the json response as follows:

{
"cents":3,
"change":[25,25,25,25,1,1,1],
"dollars":1
}
