The Data Structures and Algorithms (DSA) lesson uses an iterative approach with a cumulative variable.

Define a variable to hold the result of a cumulative operation across all elements of the array.

Apply the bitwise OR operation with the value of the cumulative variable.

The result will be the value of the cumulative variable, bitwise shifted by the number of elements minus one.

The time complexity for the solution is O(n) and its space complexity is O(1).

DSA problems are sometimes asked during tech job interviews for positions such as Software Engineer, so you can use the challenge to practice that skill.
