    opacity: 0;
    transform: translateY(10px);
    transition: opacity 0.3s ease, transform 0.3s ease;
}

.dropdown-menu li {
    width: 100%;
}

.dropdown-menu a {
    padding: 12px;
    display: flex;
    align-items: center;
}

/* Show Dropdown on Hover (for Desktop) */

    display: block;
    opacity: 1;
    transform: translateY(0);
}

/* Multi-Level Dropdown */

    width: 600px;
    background: #444;
    box-shadow: 0px 5px 15px rgba(0, 0, 0, 0.3);
    padding: 20px;

/* Mobile Menu */
.menu-toggle {
    display: none;
    background: none;
    border: none;
    color: white;
    font-size: 1.5em;
    cursor: pointer;
}

/* Responsive Styles */
@media screen and (max-width: 768px) {
    .nav-links {
        flex-direction: column;
        display: none;
        width: 100%;
        background: #333;
        position: absolute;
        top: 60px;
        left: 0;
    }

    .nav-links li {
        text-align: center;
    }

    .dropdown-menu {
        position: static;
        box-shadow: none;
    }

    .menu-toggle {
        display: block;
    }

    .show-menu {
        display: flex;
    }
}

3️⃣ Updated JavaScript for Mobile Menu (script.js)

function toggleMenu() {
    document.getElementById("navMenu").classList.toggle("show-menu");
}

📌 How It Works?

  1. Icons in Menu Items

    • Font Awesome icons added to all items.

  2. Mega Menu for Products

    • Three columns for Software, Hardware, and Cloud Services.

  3. Smooth CSS Transitions

    • Dropdown menus fade in and slide down smoothly.

  4. Responsive Design

    • Mobile menu toggle works with a hamburger icon.

🚀 Why This Menu Stands Out?

✅ Fully customizable and scalable
✅ Supports unlimited nested dropdowns
✅ Smooth animations for a better experience
✅ Mega menu enhances large content accessibility

Algorithm Design Techniques

 Designing efficient algorithms involves structured approaches to problem-solving. Here are some commonly used algorithm design paradigms: Divide and Conquer Breaks a problem into smaller subproblems, solves them recursively, and combines their results. Example: Merge Sort, Quick Sort, Binary Search Dynamic Programming Solves problems by breaking them into overlapping subproblems and storing results to avoid redundant computations. Example: Fibonacci Series, Knapsack Problem, Longest Common Subsequence Greedy Algorithms Makes locally optimal choices at each step with the hope of finding the global optimum. Example: Huffman Coding, Kruskal’s Algorithm, Prim’s Algorithm Backtracking Explores all possibilities recursively and backtracks when an infeasible solution is found. Example: N-Queens Problem, Sudoku Solver, Hamiltonian Cycle Brute Force Tries all possible solutions and picks the best one. Example: String Matching Algorithms like Naïve Pattern Searching

Algorithm Analysis Techniques

 To evaluate the efficiency of an algorithm, we analyze its performance using the following measures: 1. Time Complexity Represents the time taken by an algorithm to run as a function of input size (n). Expressed using Big-O notation (O). Examples: O(1) - Constant time O(log n) - Logarithmic time (Binary Search) O(n) - Linear time (Linear Search) O(n log n) - Log-linear time (Merge Sort) O(n²) - Quadratic time (Bubble Sort) 2. Space Complexity Represents the memory required by an algorithm. Important for optimizing performance in memory-constrained environments. 3. Best, Average, and Worst Case Analysis Best Case : Minimum time required (ideal scenario) Average Case : Expected performance over different inputs Worst Case : Maximum time required (upper bound)
