 # Fibonacci-Server
 Erlang Based Cached Fibonacci Server 
+
+To Start Server: 
+```
+> {ok,Pid}=febonnacy_server:start_link().
+```
+
+To Request Febonacci numbber:
+```
+> gen_server:call(Pid,{compute,10}).        
+55
+
+> gen_server:call(Pid,{compute,1}). 
+1
+
+> gen_server:call(Pid,{compute,0}).
+0
+
+> gen_server:call(Pid,{compute,3}).
+2
+
+> gen_server:call(Pid,{compute,10}).        
+55
+
+> gen_server:call(Pid,{compute,[0,1,3,10]}).  // list Shoud be Ordered List
+[0,1,2,55]
+
+
+```
+To get Input Count : 
+```
+> gen_server:call(Pid,count).               
+[{1,2},{3,2},{10,3},{0,2}]
+```
+To get Input Result History 
+```
+> gen_server:call(Pid,history).             
+[{1,1},{3,2},{10,55},{0,0}]
+```
+
+Again Request Febonacci number :
+```
+> gen_server:call(Pid,{compute,100}).       
+354224848179261915075
+```
+
+Check Count and History: 
+```
+> gen_server:call(Pid,count).        
+[{1,2},{3,2},{10,3},{0,2},{100,1}]
+
+> gen_server:call(Pid,history).             
+[{1,1},{3,2},{10,55},{0,0},{100,354224848179261915075}]
+```
