## CS201p Assignment 2 Solution 2023: Step-by-Step Guide

Now, let’s dive into the solution to CS201p Assignment 2 for the year 2023. We will provide a step-by-step guide on how to solve each problem in the assignment.

### Problem 1: Implement a Queue Data Structure

In this problem, you are required to implement a queue data structure using Python. A queue is a data structure that stores elements in a first-in-first-out (FIFO) manner.

To solve this problem, follow these steps:

1. Create a Python class called `Queue`.
2. Inside the `Queue` class, create an empty list called `items`.
3. Implement the `enqueue` method, which adds an element to the end of the `items` list.
4. Implement the `dequeue` method, which removes an element from the beginning of the `items` list.
5. Implement the `is_empty` method, which checks if the `items` list is empty.
6. Test your implementation by creating a `Queue` object and adding and removing elements from it.

### Problem 2: Find the Second Largest Element in a List

In this problem, you are given a list of integers, and you are required to find the second largest element in the list.

To solve this problem, follow these steps:

1. Create a Python function called `find_second_largest`.
2. Inside the `find_second_largest` function, sort the list in descending order using the `sort` method.
3. Return the second element in the sorted list.
4. Test your implementation by calling the `find_second_largest` function with a sample list.

### Problem 3: Implement a Binary Search Algorithm

In this problem, you are required to implement a binary search algorithm using Python. A binary search algorithm is an efficient algorithm for finding an item from a sorted list of items.

To solve this problem, follow these steps:

1. Create a Python function called `binary_search`.
2. Inside the `binary_search` function, define the lower and upper bounds of the search range.
1. Calculate the middle index of the search range using the formula `mid = (low + high) // 2`.
2. Compare the middle element of the list with the search value. If the middle element is equal to the search value, return its index.
3. If the middle element is greater than the search value, recursively call the `binary_search` function on the left half of the search range.
4. If the middle element is less than the search value, recursively call the `binary_search` function on the right half of the search range.
5. If the search value is not found in the list, return -1.
6. Test your implementation by calling the `binary_search` function with a sample sorted list and a search value.

### Problem 4: Calculate the Frequency of Elements in a List

In this problem, you are given a list of integers, and you are required to calculate the frequency of each element in the list.

To solve this problem, follow these steps:

1. Create a Python function called `count_frequency`.
2. Inside the `count_frequency` function, create an empty dictionary called `freq`.
3. Iterate over the list of integers and add each element to the `freq` dictionary as a key. If the key already exists in the dictionary, increment its value by 1.
4. Return the `freq` dictionary.
5. Test your implementation by calling the `count_frequency` function with a sample list.

### Problem 5: Implement a Stack Data Structure

In this problem, you are required to implement a stack data structure using Python. A stack is a data structure that stores elements in a last-in-first-out (LIFO) manner.

To solve this problem, follow these steps:

1. Create a Python class called `Stack`.
2. Inside the `Stack` class, create an empty list called `items`.
3. Implement the `push` method, which adds an element to the end of the `items` list.
4. Implement the `pop` method, which removes the last element from the `items` list.
5. Implement the `is_empty` method, which checks if the `items` list is empty.
6. Test your implementation by creating a `Stack` object and adding and removing elements from it.
