for ex: if i Pass 
5000
it should pass through that denomination like

2000*2

1000*1

5*1 like it need to check to that sequence 

Example :

1. Correct Case : Transaction amount and Denomination details match.
   1. 1. Transaction amount =3001
      2. Denomination details = DN2000#1~DN500#~DN200#5~DN100#~DN50#~DN20#~DN10#~DN5#~DN2#~DN1#~DC10#~DC5#~DC2#~DC1#1~DC20#
2. Incorrect Case : If Transaction amount and Denomination details not match.
   1. 1. Transaction amount =3000
      2. Denomination details = DN2000#2~DN500#4~DN200#5~DN100#~DN50#~DN20#~DN10#~DN5#~DN2#~DN1#~DC10#~DC5#~DC2#~DC1#~DC20#
