Chunk Arrays

Steilla Mitchel18012-Jun-2024

Given an array arr and a chunk size size, return a chunked array.

A chunked array contains the original elements in arr, but consists of subarrays each of length size. The length of the last subarray may be less than size if arr.length is not evenly divisible by size.

You may assume the array is the output of JSON.parse. In other words, it is valid JSON.

Please solve it without using lodash's _.chunk function.

I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Can you answer this question?

let's write code in the C# language to solve the Chunks Array problem.

// Method to divide the array into chunks of the specified size
public static int[][] ChunksArray(int[] array, int size)
{
    // Initialize a list to hold the chunks of arrays
    IList<int[]> list = new List<int[]>();

    // Return an empty array of arrays if the input array is empty
    if (array.Length == 0)
    {
        return list.ToArray();
    }

    // Iterate through the array, creating chunks of the specified size
    for (int i = 0; i < array.Length; i += size)
    {
        // Calculate the size of the current chunk
        int chunkSize = Math.Min(size, array.Length - i);
        // Create a new chunk and copy elements from the original array
        int[] chunk = new int[chunkSize];
        Array.Copy(array, i, chunk, 0, chunkSize);

        // Add the chunk to the list
        list.Add(chunk);
    }

    // Convert the list of chunks to an array of arrays and return it
    return list.ToArray();
}

Now call this method from the Program class.

    public class Program
    {
        public static void Main()
        {
            IList<int[]> list = new List<int[]>
            {
                new int[] { 1, 2, 3, 4, 5 },
                new int[] { 1, 9, 6, 3, 2 },
                new int[] { 8, 5, 3, 2, 6 },
                new int[]{ }
            };

            foreach (var item in list)
            {
                var data = Program.ChunksArray(item, new Random().Next(1, 6));
                Console.Write("[");
                foreach (var rows in data)
                {
                    Console.Write("[");
                    Console.Write(string.Join(", ", rows));
                    Console.Write("],");
                }
                Console.WriteLine("]");
            }

            Console.ReadLine();
        }
    }

Output :

[[1, 2, 3, 4, 5],]
[[1, 9, 6, 3, 2],]
[[8, 5],[3, 2],[6],]
[]
