3173. Bitwise OR of Adjacent Elements
Problem Explanation
Explanation:
- We are given an array of integers. We need to find the bitwise OR of each pair of adjacent elements in the array and return the resulting array.
- To calculate the bitwise OR of adjacent elements, we can simply perform the bitwise OR operation on each pair of adjacent elements in the array.
Time Complexity:
The time complexity of this approach is O(N), where N is the number of elements in the input array.
Space Complexity:
The space complexity of this approach is O(N), where N is the number of elements in the input array.
Solution Code
class Solution {
public int[] bitwiseORs(int[] arr) {
int n = arr.length;
int[] result = new int[n - 1];
for (int i = 0; i < n - 1; i++) {
result[i] = arr[i] | arr[i + 1];
}
return result;
}
