How do you solve Check if Bitwise OR Has Trailing Zeros on LeetCode?

Check if Bitwise OR Has Trailing Zeros (LeetCode #2980) can be solved using Brute Force. The optimal approach is Brute Force with undefined time complexity and undefined space complexity. Key insight: The brute force approach involves checking every possible pair of elements in the array to see if their bitwise OR has trailing zeros. This is straightforward but inefficient for larger arrays.

Algorithm

5 steps

1Step 1: Initialize a loop to iterate through each element in the array.
2Step 2: For each element, initialize another loop to check every subsequent element.
3Step 3: Calculate the bitwise OR of the two selected elements.
4Step 4: Check if the result has trailing zeros by checking if the result & 1 equals 0.
5Step 5: If a valid pair is found, return true. If no pairs are found after all iterations, return false.
