+# Quick Sort
+
+## What exactly is quicksort
+- take an element as a pivot, move all greater elements than pivot to one side and the lesser elements to the other side. Keep partioning until array is sorted. It is a divide and conquer algorithm
+- Known as the queen of all sorts.
+
+## What are the steps of the quicksort algorithm
+- Pick a pivot point
+- Partion the list by using the pivot point, move lesser elements to the left and greater elements to the right
+- Repeat until list is sorted
+
+## What is the partiion method?
+- Given ana array and an element $`x`$, put elements $`\gt x`$  to the right and $`\le x`$ to the left. This should be done in linear time
+- You can either pick the last, first, middle or random element as the pivot
+
+## Pros and Cons
+- Pros
+    - Inplace $`O(1)`$ memory
+    - Relative fast time complexity most of the time $`O(n \log n)`$
+- Cons
+    - Can result in $`O(n^2)`$ worst time complexity
+    - Hard to implement
