What is linear search in Java?
Linear search is a simple search algorithm that checks each element in a list sequentially until the desired element is found.
Can you show me a code example of linear search in Java?
Sure! Here's a basic example:
public class LinearSearch {
public static int linearSearch(int[] arr, int target) {
for (int i = 0; i < arr.length; i++) {
if (arr[i] == target) {
return i; // return the index
}
}
return -1; // return -1 if not found
}
}
What is the time complexity of linear search?
The time complexity of linear search is O(n), where n is the number of elements in the array.
When should I use linear search instead of binary search?
You should use linear search when the list is unsorted or when the list is small, as it is simpler to implement.
