Depth First Search

Depth-first search (DFS) also known as Depth First traversal is an algorithm used to traverse or search the nodes in a tree or graph data structure. Traversal usually means visiting all the nodes of a graph. DFS performs in a depth-ward manner. It uses a stack to remember the vertices it has visited. The search starts from the root node, where any arbitrary node is selected as a root node in a graph, and then each node is explored along each branch before performing backtracking. The DFS algorithm uses a recursive technique by following the idea of backtracking. DFS algorithm does this by performing an in-depth search of all the nodes by traversing in a forward direction. If the required node is not found, it starts backtracking to previously visited nodes.

### Implementing a Stack in C

Stacks are a fundamental data structure used in various applications in computer science. In this example, we will demonstrate how to implement a stack using an array in the C programming language.

A stack operates on a Last-In-First-Out (LIFO) principle, where the most recently added item is the first one to be removed.

#### Step-by-Step Implementation

1. **Initialization:**
- We will use an array of integers, `int[100]`, to store the stack elements.
- An integer variable `top` will keep track of the index of the topmost element. It is initialized to `-1`, indicating that the stack is empty.

2. **Defining Functions:**
- Three primary functions will be implemented: `push()`, `pop()`, and `isEmpty()`.

#### Function Definitions

1. **push(int v):**
- This function adds an integer `v` to the top of the stack.
- **Error Handling:** If the stack is full (i.e., `top >= 99`), it prints an error message and returns `0`.
- Otherwise, it increments the `top`, adds `v` to `stack[top]`, and returns `0`.

2. **pop():**
- This function removes and returns the topmost element from the stack.
- **Error Handling:** If the stack is empty (i.e., `top < 0`), it prints an error message and returns `0`.
- Otherwise, it returns the value of `stack[top]` and decrements the `top`.

3. **isEmpty():**
- This function checks if the stack is empty.
- It returns `0` if the stack is empty (`top < 0`) and `1` otherwise.

#### Implementation Code

```c
#include <stdio.h>

int stack[100];
int top = -1; // The stack is initially empty

int push(int v) {
if (top >= 99) {
printf("Error: Stack Overflow\n");
return 0;
} else {
top++;
stack[top] = v;
return 0;
}
}

int pop() {
if (top < 0) {
printf("Error: Stack Underflow\n");
return 0;
} else {
return stack[top--];
}
}
