+# Paths & Tours
+
+Suppose we have the following control flow graph (CFG):
+
+```
+-> (1) -> (2) -> (3) -> (5) -> ((6))
+ | ^ ^
+ | | /
+ | | /
+ v | /
+ (4)
+```
+
+Let's break it down!
+
+## Simple Paths
+
+| Lengths | Paths |
+|----------|-------------------------------------------------------|
+| 0 | [1], [2], [3], [4], [5], [6] |
+| 1 | [1,2], [2,3], [3,4], [3,5], [4,5], [5,6] |
+| 2 | [1,2,3], [2,3,4], [2,3,5], [3,4,5], [3,5,6] |
+| 3 | [1,2,3,4], [1,2,3,5], [2,3,4,5], [2,3,5,6], [3,4,5,6] |
+| 4 | [1,2,3,4,5], [1,2,3,5,6], [2,3,4,5,6] |
+| 5 | [1,2,3,4,5,6] |
+
+## Prime Paths
