 - [X] Execution
   - [ ] Timeout

 ### Execution
 
 Use the command to execute the code. 
 Issue is, because BF is a *turing complete* language, there is no way to know if the program will terminate or not. Hence for now, the command may lead to infinite execution. 
-Additionally, all input is done before program execution (If the program requests for input that hasn't been provided, `zero` is fed to it).
+If the program requires input, it will be requested as a prompt.
 
 TODO: Implement a timeout.

+### Changelog
+
+#### 0.5.0
+
+- Request input as required during execution
+- Using array-based indexing. This implies that only positive indices upto 30k are supported.
