+## Outline
+
+We're working on exercise 2 from [2026.07.31](../2026.07.31/overview.md).
+The exercise and starter file is included again below for convenience.
+
+In a *weighted* road network, return all possible paths that a car can take to
+reach point A to point B. For each path, also sum up the total weight that
+taking that path requires.
+
+Your algorithm should take the starting and ending points, and return a list
+of tuples. Each tuple should contain the traversal from point A to point B,
+followed by the total weight.
+
+In this fictitious graph, calling `possible_paths("Santa Ana", "San Francisco")`
+should yield the return below.
+
+```python
+graph = {
+    'Santa Ana': {
+        'Los Angeles': 5,
+        'Palm Springs': 50
+    },
+    'Los Angeles': {
+        'San Francisco': 25,
+        'Santa Ana': 5
+    },
+    'Palm Springs': {
+        'San Francisco': 30,
+        'Santa Ana': 50
+    },
+    'San Francisco': {
+        'Los Angeles': 25,
+        'Palm Springs': 30
+    } 
+}
+```
+
+```
+[
+    (
+        ["Santa Ana", "Los Angeles", "San Francisco"],
+        30
+    ),
+    (
+        ["Santa Ana", "Palm Springs", "San Francisco"],
+        80
+    )
+]
+```
