    Searching algorithms are essential for retrieving elements from data structures. They are broadly classified into two categories: Sequential Search and Interval Search. Sequential search involves traversing the list or array sequentially and checking each element, while interval search is designed for sorted data structures and is more efficient.

    Linear Search

    Linear search is a simple algorithm that traverses the array and compares each element with the target value. If a match is found, the index is returned; otherwise, -1 is returned. Here is an example of linear search in Java:

    class GFG {
    public static int search(int arr[], int x) {
    int n = arr.length;
    for (int i = 0; i < n; i++) {
    if (arr[i] == x)
    return i;
    }
    return -1;
    }

    public static void main(String args[]) {
    int arr[] = { 2, 3, 4, 10, 40 };
    int x = 10;
    int result = search(arr, x);
    if (result == -1)
    System.out.print("Element is not present in array");
    else
    System.out.print("Element is present at index " + result);
    }
    }
    Copié !

    String Search Algorithms for Large Texts with Java - Baeldung

    Introduction

    In this article, we’ll show several algorithms for searching for a pattern in a large text. We’ll describe each algorithm with provided code and simple mathematical background. Notice that provided algorithms are not the best way to do a ful…

    Algorithms

    We’ll start with a naive text search algorithm which is the most intuitive one and helps to discover other advanced problems associated with that task.

    Conclusion

    In this article, we presented several algorithms for text search. Since several algorithms require stronger mathematical background, we tried to represent the main idea beneath each algorithm and provide it in a simple manner. And, as always, the so…
