can u solve this question
▎Title: 201. Bitwise AND of Numbers Range
Difficulty: Medium
Denoscription:
Given two integers
Example 1:
Explanation:
Bitwise AND of all numbers in the range [5, 7] is 4 (binary 100).
Example 2:
Example 3:
Explanation:
There is no common bit position that stays 1 throughout the range, so the result is 0.
Constraints:
▎Title: 201. Bitwise AND of Numbers Range
Difficulty: Medium
Denoscription:
Given two integers
left and right that represent the range [left, right], return the bitwise AND of all numbers in this range, inclusive.Example 1:
Input: left = 5, right = 7
Output: 4
Explanation:
5 = 101
6 = 110
7 = 111
Bitwise AND of all numbers in the range [5, 7] is 4 (binary 100).
Example 2:
Input: left = 0, right = 0
Output: 0
Example 3:
Input: left = 1, right = 2147483647
Output: 0
Explanation:
There is no common bit position that stays 1 throughout the range, so the result is 0.
Constraints:
0 <= left <= right <= 2^31 - 1
can u solve this question? with bit manipulation in constant extra space and linear time complexity

▎Title: 137. Single Number II
Difficulty: Medium
Denoscription:
Given an integer array
nums where every element appears three times except for one, which appears exactly once, find the single element and return it.You must implement a solution with a linear runtime complexity and use only constant extra space.
Example 1:
Input:
nums = [2,2,3,2] Output:

•
1 <= nums.length <= 3 * 10^4•
-2^31 <= nums[i] <= 2^31 - 1• Each element in
nums appears exactly three times except for one element which appears once.❤3
🚨 16 Billion Logins Leaked in Historic Data Breach
Cybersecurity researchers have uncovered one of the largest breaches ever. Over 16 billion login credentials—including social media, corporate, VPN, and email accounts—have been leaked online. The data is recent and weaponizable, gathered through malware from unsecured databases. It includes:
* Usernames, passwords, and URLs
* Apple accounts, Telegram-linked accounts, and more
* Datasets originating from the Russian Federation
Experts warn this leak is a blueprint for mass exploitation, enabling identity theft, phishing, and account takeovers.
