???? Solution: Pinned in the comments.

In today's LeetCode daily challenge, we solve the Minimum Array End problem. The solution is implemented in Java.

???? Problem Description:
Given an integer n (length of an array) and an integer x (starting element), the goal is to find the smallest possible last element in an array where each element is either equal to or a bitwise OR with the previous one. The task is to determine the minimum possible last element given these constraints.

???? Key Points:

Bitwise Operations: The solution heavily uses bitwise OR and checks individual bits.
Optimization with Shifts: Using bit shifts to modify x based on bits in remaining elements.
Iterative Updates: By updating each bit position conditionally, we achieve the minimum possible result.
???? Code Explanation:

Initial Setup: Initialize minLastElement with x and set the count of remaining elements.
Bit Manipulation Loop: For each bit, if it's zero in x, update minLastElement with OR operations based on elementsRemaining.
Return Result: Return the computed minimum last element after processing all bits.
