Solving the Reverse Array Problem in CodeChef: A Guide for C- Developers

If you’ve found yourself stuck on the CodeChef problem for reversing an array, you’re not alone. One common issue arises from reading user input incorrectly, leading to unexpected results in your program. In this guide, we're going to break down the problem and provide a clear solution to ensure you can read input correctly in C-.

The Problem

You might be wanting to read an array of integers from user input in C-, and reverse that input correctly. For example, if a user enters:

The expected output should be:

However, you may encounter unexpected character codes as output instead of the actual numbers. This happens due to how you read inputs from the console.

Identifying the Issues

Upon reviewing your initial code, there are two primary issues causing the misreading of the array elements:

Ignoring Spaces: Spaces between the input numbers are not being handled, causing trouble in reading separate values correctly.

Character Codes Instead of Numeric Values: By using Console.Read(), the method returns the ASCII character codes instead of the corresponding integer values.

To resolve these issues, let’s look at a step-by-step solution.

The Solution

Here's how to effectively read the user input and reverse the array:

Step 1: Correct Input Reading

Instead of reading directly from the console with Console.Read(), we will utilize Console.ReadLine() and then process the string input.

You can manually handle the spaces while extracting each digit from the input.

Updated Code

Here’s a revised version of your code that addresses both issues:

Explanation of the Code

Reading the Count: The first line captures how many numbers will be inputted.

Reading and Splitting Input: The Console.ReadLine() method reads the entire line as a string, and Split(' ') divides that string into an array based on spaces.

Conversion: Each split string is converted into an integer and stored in the array.

Reversing the Output: Finally, we iterate over the array in reverse and print the integers.

Conclusion

By following these steps, you’ll be able to correctly handle the input for the reverse array problem on CodeChef using C-. Remember, handling input carefully can save you from a lot of headaches and ensure your program behaves as expected. Happy coding!
