# Lab01: warm-up1

This is a warm-up lab that prepares you with the basic techniques 
used throughout this course. It is also a good chance to familiarize
yourself with our submission and scoring system.

In this problem, your task is to defuse the bomb and get the flag.
The binary _bomb_, is an executable that consists of multiple _phases_.
Each phase expects you to enter a particular string (i.e., password) on stdin.
If you enter the expected phrase, then the bomb is defused. Otherwise,
it explodes, and you get _five_ points **deducted**. A thorough 
understanding of how each phase works at the binary level
is required to solve this challenge without losing your points.

Note: you must maintain the Internet connection when you are solving
this problem as it will update your progress (i.e., bomb
defused/exploded) to the submission site, so be careful and not let
the bomb explode! But be **creative** yet **careful** not to lose
any points!

  - [5 points] whenever we notice that you explode a bomb
