Try to identify the problem..... button may fail because of
various reasons like...
1) It is not ON yet.
2) Technical problem in that button.
We should create a solution space for the above scenarios.
For case-1) Try to switch it ON.If its not gettion ON
still, may be bcoz of no charge in battery. So charge /
change the cell and switch it ON.
For case-2) Assume your button 2 is not working, use button
3 and then press -1 to get the result.
