Do you have experience studying the book "Grokking Algorithms"?

Yes, the book "Grokking Algorithms" is a popular introduction to algorithms and data structures, written in simple and accessible language. It helps understand key concepts such as sorting, searching, recursion, data structures (lists, trees, hash tables), and graph algorithms.

For those studying Java, the book is useful as a basic guide that can be complemented with practice implementing algorithms in Java. For example, after reading, you can try implementing the quicksort algorithm:

public class QuickSort {
    public static void quickSort(int[] arr, int low, int high) {
        if (low < high) {
            int pi = partition(arr, low, high);
            quickSort(arr, low, pi - 1);
            quickSort(arr, pi + 1, high);
        }
    }

    private static int partition(int[] arr, int low, int high) {
        int pivot = arr[high];
        int i = low - 1;
        for (int j = low; j < high; j++) {
            if (arr[j] < pivot) {
                i++;
                int temp = arr[i];
                arr[i] = arr[j];
                arr[j] = temp;
            }
        }
        int temp = arr[i + 1];
        arr[i + 1] = arr[high];
        arr[high] = temp;
        return i + 1;
    }
}

Thus, the book serves as a good starting point for understanding algorithmic concepts.
