Question

**Consider the following code:**

```c
int x = 0x2020;
int *y = &x;
int **z = &y;
*y += 8;
int w = **z;
```

Suppose the compiler puts `x` at address `0x2000`, `y` at address `0x2008`, `z` at address `0x2010`, and `w` at address `0x2018`.

Use this code to answer the next 4 questions.

---

The code snippet exhibits the use of pointers and pointer manipulation in C programming. Here’s a brief explanation:

- `x` is assigned the hexadecimal value `0x2020`.
- `y` is a pointer that stores the address of `x`.
- `z` is a pointer to a pointer, storing the address of `y`.
- The line `*y += 8;` increments the value pointed to by `y` (i.e., `x`) by 8.
- `w` stores the value pointed to by `z`, which is the same as `x` now increased by 8.

The memory addresses shown are just hypothetical and help illustrate where each variable resides during execution.

Q1: We define the capacity of a path in a weighted graph G(V, E) to be the minimum weight of an edge along that path. For example, the capacity of the path [V0, V1, V2] in the graph below is 5 and the capacity of the path V1, V0, V3, V2 is 3. A maximum-capacity path between u and v is a simple path between u and v whose capacity is larger than or equal to those of all paths from u to v. In the graph below, the maximum capacity path from V0 to V3 is [V0, V1, V2, V3]. (a) Show that if [a, b, ... , u, v] is a maximum-capacity path from a to v, then a maximum- capacity path from a to u followed by the edge (u, v) is a maximum-capacity path from a to v. (b) Is it true that if [a, b, c, u, v] is a maximum-capacity path from a to v, then [a, b, c, u] is a maximum-capacity path from a to u? Why? (c) Can you think of an algorithm you have seen before that can be modified to find the maximum-capacity paths from a particular vertex s to all other vertices in the graph? How?
