100 | | -### Welcome |
101 | | -Welcome to the problem-solving galaxy. |
102 | | - |
103 | | -### Problem Solving |
104 | | -In this galaxy, we will focus on real-world coding related problem-solving. |
105 | | - |
106 | | -The problem-solving means, we will take a small programming problem. We will think about the process of solving the problem and then we will solve it. |
107 | | - |
108 | | -## Explanation |
109 | | -After the solution, we will explain the answer. Convey the concept and strategy to solve it. |
110 | | - |
111 | | -### Purpose |
112 | | -Solving coding problems helps you to think about the problem. It will make you a better developer. Moreover, if you want to participate in a programming contest, you need to practice problem-solving. |
113 | 101 |
|
114 | | -### Interview |
115 | | -Besides, large companies like Google, Facebook, Amazon, Uber, etc. ask a lot of problem-solving related questions in their job interview.<br><br>If you want to work any of these large companies, you should practice problem-solving. |
