XOR Operation in Farmer Land Ownership

In this article, we will explore the concept of XOR operation in determining the total land owned by farmers in a given area. We will discuss the logic behind this operation and then proceed to implement it using Python code.

Introduction

XOR, also known as exclusive OR, is a logical operation that returns true only when the inputs differ. It is commonly used in various fields, including computer science and mathematics. In the Context of determining land ownership, we can utilize the XOR operation to find the total land owned by each farmer Based on the previous farmer's ownership.

Understanding the Question

The problem at HAND involves a group of farmers, each with a certain number of lands owned. We need to calculate the sum of land owned by all the farmers using the XOR operation. The number of farmers and their land ownership data will be provided as input.

Logic Explanation

To solve this problem, we need to determine the ownership of land for each farmer by performing the XOR operation. The XOR operation works by comparing the binary representation of two values and returning the result where the bits differ.

Let's consider an example where there are three farmers. The first farmer has 1 land, the Second farmer has 2 lands, and the third farmer has 3 lands. Starting from the second farmer, we will calculate the XOR of his land ownership with the previous farmer's land ownership.

For the second farmer, the XOR operation between 1 (previous farmer's ownership) and 2 (Current farmer's ownership) will result in 3. Similarly, for the third farmer, the XOR operation between 3 (previous farmer's ownership) and 3 (current farmer's ownership) will result in 0.

We will store the result of each XOR operation in a vector or an array. Finally, we will calculate the sum of all the elements in the vector to obtain the total land owned by the farmers.

Implementation Steps

  1. Take the input for the number of farmers and initialize the land ownership vector with a default value of 1.
  2. Traverse the vector starting from the second element.
  3. Calculate the XOR operation between the previous farmer's ownership and the current farmer's ownership.
  4. Store the result of the XOR operation in the vector.
  5. Calculate the sum of all the elements in the vector.
  6. Print the sum as the output.

Test Cases

Let's run this code for various test cases to validate its functionality.

  1. Input: Number of farmers (n) = 1 Output: 1

  2. Input: Number of farmers (n) = 3 Output: 4

Conclusion

In this article, we explored the concept of using the XOR operation to determine the total land owned by farmers. We discussed the logic behind the operation and implemented it using Python code. By understanding the logic, You can Apply it in any programming language.

Python Code

# Python code for XOR Operation in Farmer Land Ownership

n = int(input("Enter the number of farmers: "))
farmers = [1]

for i in range(2, n+1):
    farmers.append(farmers[-1] ^ i)

total_land = sum(farmers)
print("Total land owned by farmers: ", total_land)

Question and Logic Recap

In the given problem, we need to calculate the total land owned by farmers using the XOR operation. By performing the XOR operation between the previous farmer's ownership and the current farmer's ownership, we can determine the land ownership for each farmer. The sum of all the land ownership values will give us the total land owned by the farmers.

FAQ:

Q: What is the XOR operation? A: XOR, or exclusive OR, is a logical operation that returns true only when the inputs differ.

Q: How does the XOR operation work in determining land ownership? A: The XOR operation compares the binary representation of land ownership values for consecutive farmers and returns the result where the bits differ.

Q: How can I implement this logic in a different programming language? A: The logic can be implemented in any programming language by following the steps described and modifying the syntax and data structures accordingly.
