## List

When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]

I found Algorithm is fascinating which I want to keep exploring for fun. This is my learning notes about Algorithm, based on

- Rutegrs CS course 520,

- Coursera "Algorithm" by Princeton,

- LeetCode and many others.
