2635. Apply Transform Over Each Element in Array
Problem Explanation
Explanation
To solve this problem, we can iterate through the input array and apply the given mapping function to each element. We will create a new array to store the transformed elements. We will pass the current element and its index to the mapping function and store the result in the new array. Finally, we will return the new array containing the transformed elements.
- Time complexity: O(N) where N is the number of elements in the input array.
- Space complexity: O(N) to store the new array.
Solution Code
public int[] applyTransform(int[] arr, BiFunction<Integer, Integer, Integer> fn) {
int[] result = new int[arr.length];
for (int i = 0; i < arr.length; i++) {
result[i] = fn.apply(arr[i], i);
}
return result;
