2804. Array Prototype ForEach
Problem Explanation
Explanation
In this problem, we are tasked with implementing a function similar to the forEach method available for arrays in JavaScript. The function will iterate over each element of the given array and apply a provided callback function to each element.
Algorithmic Idea
- Iterate over each element in the array.
- Apply the provided callback function to each element.
Time Complexity
The time complexity of this algorithm is O(n), where n is the number of elements in the input array.
Space Complexity
The space complexity of this algorithm is O(1) as we are not using any extra space proportional to the input size.
Solution Code
public class ArrayPrototypeForEach {
public static void forEach(int[] arr, IntConsumer action) {
for (int num : arr) {
action.accept(num);
}
}
